 You can switch off implicit conversions by defining `JSON_USE_IMPLICIT_CONVERSIONS` to `0` before including the `json.hpp` header. When using CMake, you can also achieve this by setting the option `JSON_ImplicitConversions` to `OFF`.

 1. Comments are not part of the [JSON specification](https://tools.ietf.org/html/rfc8259). You may argue that `//` or `/* */` are allowed in JavaScript, but JSON is not JavaScript.
 2. This was not an oversight: Douglas Crockford [wrote on this](https://plus.google.com/118095276221607585885/posts/RK8qyGVaGSr) in May 2012:

 # basic_json::dump
 ```cpp
 string_t dump(const int indent = -1,
              const char indent_char = ' ',
              const bool ensure_ascii = false,
              const error_handler_t error_handler = error_handler_t::strict) const
 ```
 Serialization function for JSON values. The function tries to mimic
 Python's `json.dumps()` function, and currently supports its `indent`
 and `ensure_ascii` parameters.
 ## Parameters
 `indent` (in)
 :   If `indent` is nonnegative, then array elements and object
    members will be pretty-printed with that indent level. An indent level of
    `0` will only insert newlines. `-1` (the default) selects the most compact
    representation.
 `indent_char` (in)
 :   The character to use for indentation if `indent` is
    greater than `0`. The default is ` ` (space).
 `ensure_ascii` (in)
 :   If `ensure_ascii` is true, all non-ASCII characters
    in the output are escaped with `\uXXXX` sequences, and the result consists
    of ASCII characters only.
 `error_handler` (in)
 :   how to react on decoding errors; there are three
    possible values: `strict` (throws and exception in case a decoding error
    occurs; default), `replace` (replace invalid UTF-8 sequences with U+FFFD),
    and `ignore` (ignore invalid UTF-8 sequences during serialization; all
    bytes are copied to the output unchanged).
 ## Return value
 string containing the serialization of the JSON value
 ## Exception safety
 Strong guarantee: if an exception is thrown, there are no
 changes to any JSON value.
 ## Complexity
 Linear.
 ## Notes
 Binary values are serialized as object containing two keys:
 - "bytes": an array of bytes as integers
 - "subtype": the subtype as integer or `#!json null` if the binary has no subtype
 ## Example
 ??? example
    The following example shows the effect of different `indent`,
    `indent_char`, and `ensure_ascii` parameters to the result of the
    serialization.
    ```cpp
    --8<-- "examples/dump.cpp"

 ```
 1. Deserialize from a compatible input.
 2. Deserialize from a pair of character iterators
    The value_type of the iterator must be a integral type with size of 1, 2 or
    4 bytes, which will be interpreted respectively as UTF-8, UTF-16 and UTF-32.
 ## Template parameters
 `InputType`
 :   A compatible input, for instance:
    - an `std::istream` object
    - a `FILE` pointer
    - a C-style array of characters
    - a pointer to a null-terminated string of single byte characters
    - an object `obj` for which `begin(obj)` and `end(obj)` produces a valid pair of
      iterators.
 `IteratorType`
 :   Description
 ## Parameters
 `i` (in)
 :   Input to parse from.
 `cb` (in)
 :   a parser callback function of type `parser_callback_t`
    which is used to control the deserialization by filtering unwanted values
    (optional)
 `allow_exceptions` (in)
 :    whether to throw exceptions in case of a parse error (optional, `#!cpp true` by default)
 `ignore_comments` (in)
 :   whether comments should be ignored and treated
    like whitespace (`#!cpp true`) or yield a parse error (`#!cpp false`); (optional, `#!cpp false` by
    default)
 `first` (in)
 :   iterator to start of character range
 `last` (in)
 :   iterator to end of character range
 ## Return value
 Deserialized JSON value; in case of a parse error and `allow_exceptions`
 set to `#!cpp false`, the return value will be `value_t::discarded`.
 ## Exception safety
 ## Complexity
 Linear in the length of the input. The parser is a predictive
 LL(1) parser. The complexity can be higher if the parser callback function
 `cb` or reading from (1) the input `i` or (2) the iterator range [`first`, `last`] has a super-linear complexity.
 ## Notes
 (1) A UTF-8 byte order mark is silently ignored.
 ## Examples
 ??? example
    The example below demonstrates the `parse()` function reading
    from an array.
    ```cpp
    --8<-- "examples/parse__array__parser_callback_t.cpp"

 # Comments
 This library does not support comments *by default*. It does so for three reasons:
 1. Comments are not part of the [JSON specification](https://tools.ietf.org/html/rfc8259). You may argue that `//` or `/* */` are allowed in JavaScript, but JSON is not JavaScript.
 2. This was not an oversight: Douglas Crockford [wrote on this](https://plus.google.com/118095276221607585885/posts/RK8qyGVaGSr) in May 2012:
 	> 	I removed comments from JSON because I saw people were using them to hold parsing directives, a practice which would have destroyed interoperability.  I know that the lack of comments makes some people sad, but it shouldn't. 
 	> 	Suppose you are using JSON to keep configuration files, which you would like to annotate. Go ahead and insert all the comments you like. Then pipe it through JSMin before handing it to your JSON parser.
 3. It is dangerous for interoperability if some libraries would add comment support while others don't. Please check [The Harmful Consequences of the Robustness Principle](https://tools.ietf.org/html/draft-iab-protocol-maintenance-01) on this.
 However, you can pass set parameter `ignore_comments` to `#!c true` in the parse function to ignore `//` or `/* */` comments. Comments will then be treated as whitespace.
 !!! example
    Consider the following JSON with comments.
    ```json
    {
        // update in 2006: removed Pluto
        "planets": ["Mercury", "Venus", "Earth", "Mars",
                    "Jupiter", "Uranus", "Neptune" /*, "Pluto" */]
    }
    ```
    When calling `parse` without additional argument, a parse error exception is thrown. If `skip_comments` is set to `#! true`, the comments are skipped during parsing:
    ```cpp
    #include <iostream>
    #include "json.hpp"
    using json = nlohmann::json;
    int main()

 # Checked access: at
 ## Overview
 The `#!cpp at()` member function performs checked access; that is, it returns a reference to the desired value if it exists and throws a [`basic_json::out_of_range` exception](../../home/exceptions.md#out-of-range) otherwise.
 ??? example
    Consider the following JSON value:

 # Unchecked access: operator[]
 ## Overview
 Elements in a JSON object and a JSON array can be accessed via `#!cpp operator[]` similar to a `#!cpp std::map` and a `#!cpp std::vector`, respectively.
 ??? example
    Consider the following JSON value:
    ```json
    {
        "name": "Mary Smith",
        "age": 42,
        "hobbies": ["hiking", "reading"]
    }
    ```
    Assume the value is parsed to a `json` variable `j`.
    | expression | value |
    | ---------- | ----- |
    | `#!cpp j`  | `#!json {"name": "Mary Smith", "age": 42, "hobbies": ["hiking", "reading"]}` |
    | `#!cpp j["name"]`  | `#!json "Mary Smith"` |
    | `#!cpp j["age"]`  | `#!json 42` |
    | `#!cpp j["hobbies"]`  | `#!json ["hiking", "reading"]` |
    | `#!cpp j["hobbies"][0]`  | `#!json "hiking"` |
    | `#!cpp j["hobbies"][1]`  | `#!json "reading"` |
 The return value is a reference, so it can be modify the original value. In case the passed object key is non-existing, a `#!json null` value is inserted which can be immediately be overwritten.
 ??? example
    ```cpp
    j["name"] = "John Smith";
    j["maidenName"] = "Jones";
    ```
    This code produces the following JSON value:
    ```json
    {
        "name": "John Smith",
        "maidenName": "Jones",
        "age": 42,
        "hobbies": ["hiking", "reading"]
    }
    ```
 When accessing an invalid index (i.e., and index greater than or equal to the array size), the JSON array is resized such that the passed index is the new maximal index. Intermediate values are filled with `#!json null`.
 ??? example
    ```cpp
    j["hobbies"][0] = "running";
    j["hobbies"][3] = "cooking";
    ```
    This code produces the following JSON value:
    ```json
    {
        "name": "John Smith",
        "maidenName": "Jones",
        "age": 42,
        "hobbies": ["running", "reading", null, "cooking"]
    }
    ```
 ## Notes
 !!! info "Design rationale"
    The library behaves differently to `#!cpp std::vector` and `#!cpp std::map`:
    - `#!cpp std::vector::operator[]` never inserts a new element.
    - `#!cpp std::map::operator[]` is not available for const values.
    The type `#!cpp json` wraps all JSON value types. It would be impossible to remove `operator[]` for const objects. At the same time, inserting elements for non-const objects is really convenient as it avoids awkward `insert` calls. To this end, we decided to have an inserting non-const behavior for both arrays and objects.
 !!! info
    The access is unchecked. In case the passed object key does not exist or the passed array index is invalid, no exception is thrown.
 !!! danger
    - It is **undefined behavior** to access a const object with a non-existing key.
    - It is **undefined behavior** to access a const array with an invalid index.
    - In debug mode, an **assertion** will fire in both cases. You can disable assertions by defining the preprocessor symbol `#!cpp NDEBUG` or redefine the macro [`JSON_ASSERT(x)`](../macros.md#json_assertx).
 !!! failure "Exceptions"
    `operator[]` can only be used with objects (with a string argument) or with arrays (with a numeric argument). For other types, a [`basic_json::type_error`](../../home/exceptions.md#jsonexceptiontype_error305) is thrown.

 # Object Order
 The [JSON standard](https://tools.ietf.org/html/rfc8259.html) defines objects as "an unordered collection of zero or more name/value pairs". As such, an implementation does not need to preserve any specific order of object keys.
 The default type `nlohmann::json` uses a `std::map` to store JSON objects, and thus stores object keys **sorted alphabetically**.
 ??? example
    ```cpp
    #include <iostream>
    #include "json.hpp"
    using json = nlohmann::json;
    int main()
    {
        json j;
        j["one"] = 1;
        j["two"] = 2;
        j["three"] = 3;
        std::cout << j.dump(2) << '\n';
    }
    ```
    Output:
    ```json
    {
      "one": 1,
      "three": 3,
      "two": 2
    }
    ```
 If you do want to preserve the **insertion order**, you can try the type [`nlohmann::ordered_json`](https://github.com/nlohmann/json/issues/2179).
 ??? example
    ```cpp
    #include <iostream>
    #include <nlohmann/json.hpp>

        j["two"] = 2;
        j["three"] = 3;
        std::cout << j.dump(2) << '\n';
    }

 ## Limitations
 ### Comments
 !!! question "Questions"
 	- Why does the library not support comments?
 	- Can you add support for JSON5/JSONC/HOCON so that comments are supported?
 This library does not support comments. It does so for three reasons:
 1. Comments are not part of the [JSON specification](https://tools.ietf.org/html/rfc8259). You may argue that `//` or `/* */` are allowed in JavaScript, but JSON is not JavaScript.
 2. This was not an oversight: Douglas Crockford [wrote on this](https://plus.google.com/118095276221607585885/posts/RK8qyGVaGSr) in May 2012:
 	> 	I removed comments from JSON because I saw people were using them to hold parsing directives, a practice which would have destroyed interoperability.  I know that the lack of comments makes some people sad, but it shouldn't. 
 	> 	Suppose you are using JSON to keep configuration files, which you would like to annotate. Go ahead and insert all the comments you like. Then pipe it through JSMin before handing it to your JSON parser.
 3. It is dangerous for interoperability if some libraries would add comment support while others don't. Please check [The Harmful Consequences of the Robustness Principle](https://tools.ietf.org/html/draft-iab-protocol-maintenance-01) on this.
 This library will not support comments in the future. If you wish to use comments, I see three options:
 1. Strip comments before using this library.
 2. Use a different JSON library with comment support.
 3. Use a format that natively supports comments (e.g., YAML or JSON5).

 ## Serialization issues
 ### Order of object keys
 !!! question "Questions"
 	- Why are object keys sorted?
 	- Why is the insertion order of object keys not preserved?
 By default, the library does not preserve the **insertion order of object elements**. This is standards-compliant, as the [JSON standard](https://tools.ietf.org/html/rfc8259.html) defines objects as "an unordered collection of zero or more name/value pairs".
 If you do want to preserve the insertion order, you can specialize the object type with containers like [`tsl::ordered_map`](https://github.com/Tessil/ordered-map) ([integration](https://github.com/nlohmann/json/issues/546#issuecomment-304447518)) or [`nlohmann::fifo_map`](https://github.com/nlohmann/fifo_map) ([integration](https://github.com/nlohmann/json/issues/485#issuecomment-333652309)).
