### JSONObject

* \[x: string]

  ```ts

### JSONArray

* \_\_@iterator\@410

  Iterator

  ```ts
  () => IterableIterator<JSONValue>
  ```

* \_\_@unscopables\@412

  Returns an object whose properties have the value 'true' when they will be absent when used in a 'with' statement.

  ```ts
  () => { copyWithin: boolean; entries: boolean; fill: boolean; find: boolean; findIndex: boolean; keys: boolean; values: boolean; }
  ```

* at

  ```ts
  (index: number) => JSONValue
  ```

* concat

  Combines two or more arrays. This method returns a new array without modifying any existing arrays.

  ```ts
  { (...items: ConcatArray<JSONValue>[]): JSONValue[]; (...items: (JSONValue | ConcatArray<JSONValue>)[]): JSONValue[]; }
  ```

* copyWithin

  Returns the this object after copying a section of the array identified by start and end to the same array starting at position target

  ```ts
  (target: number, start: number, end?: number) => JSONArray
  ```

* entries

  Returns an iterable of key, value pairs for every entry in the array

  ```ts
  () => IterableIterator<[number, JSONValue]>
  ```

* every

  Determines whether all the members of an array satisfy the specified test.

  ```ts
  { <S extends JSONValue>(predicate: (value: JSONValue, index: number, array: JSONValue[]) => value is S, thisArg?: any): this is S[]; (predicate: (value: JSONValue, index: number, array: JSONValue[]) => unknown, thisArg?: any): boolean; }
  ```

* fill

  Changes all array elements from \`start\` to \`end\` index to a static \`value\` and returns the modified array

  ```ts
  (value: JSONValue, start?: number, end?: number) => JSONArray
  ```

* filter

  Returns the elements of an array that meet the condition specified in a callback function.

  ```ts
  { <S extends JSONValue>(predicate: (value: JSONValue, index: number, array: JSONValue[]) => value is S, thisArg?: any): S[]; (predicate: (value: JSONValue, index: number, array: JSONValue[]) => unknown, thisArg?: any): JSONValue[]; }
  ```

* find

  Returns the value of the first element in the array where predicate is true, and undefined otherwise.

  ```ts
  { <S extends JSONValue>(predicate: (this: void, value: JSONValue, index: number, obj: JSONValue[]) => value is S, thisArg?: any): S; (predicate: (value: JSONValue, index: number, obj: JSONValue[]) => unknown, thisArg?: any): JSONValue; }
  ```

* findIndex

  Returns the index of the first element in the array where predicate is true, and -1 otherwise.

  ```ts
  (predicate: (value: JSONValue, index: number, obj: JSONValue[]) => unknown, thisArg?: any) => number
  ```

* flat

  Returns a new array with all sub-array elements concatenated into it recursively up to the specified depth.

  ```ts
  <A, D extends number = 1>(this: A, depth?: D) => FlatArray<A, D>[]
  ```

* flatMap

  Calls a defined callback function on each element of an array. Then, flattens the result into a new array. This is identical to a map followed by flat with depth 1.

  ```ts
  <U, This = undefined>(callback: (this: This, value: JSONValue, index: number, array: JSONValue[]) => U | readonly U[], thisArg?: This) => U[]
  ```

* forEach

  Performs the specified action for each element in an array.

  ```ts
  (callbackfn: (value: JSONValue, index: number, array: JSONValue[]) => void, thisArg?: any) => void
  ```

* includes

  Determines whether an array includes a certain element, returning true or false as appropriate.

  ```ts
  (searchElement: JSONValue, fromIndex?: number) => boolean
  ```

* indexOf

  Returns the index of the first occurrence of a value in an array, or -1 if it is not present.

  ```ts
  (searchElement: JSONValue, fromIndex?: number) => number
  ```

* join

  Adds all the elements of an array into a string, separated by the specified separator string.

  ```ts
  (separator?: string) => string
  ```

* keys

  Returns an iterable of keys in the array

  ```ts
  () => IterableIterator<number>
  ```

* lastIndexOf

  Returns the index of the last occurrence of a specified value in an array, or -1 if it is not present.

  ```ts
  (searchElement: JSONValue, fromIndex?: number) => number
  ```

* length

  Gets or sets the length of the array. This is a number one higher than the highest index in the array.

  ```ts
  number
  ```

* map

  Calls a defined callback function on each element of an array, and returns an array that contains the results.

  ```ts
  <U>(callbackfn: (value: JSONValue, index: number, array: JSONValue[]) => U, thisArg?: any) => U[]
  ```

* pop

  Removes the last element from an array and returns it. If the array is empty, undefined is returned and the array is not modified.

  ```ts
  () => JSONValue
  ```

* push

  Appends new elements to the end of an array, and returns the new length of the array.

  ```ts
  (...items: JSONValue[]) => number
  ```

* reduce

  Calls the specified callback function for all the elements in an array. The return value of the callback function is the accumulated result, and is provided as an argument in the next call to the callback function.

  ```ts
  { (callbackfn: (previousValue: JSONValue, currentValue: JSONValue, currentIndex: number, array: JSONValue[]) => JSONValue): JSONValue; (callbackfn: (previousValue: JSONValue, currentValue: JSONValue, currentIndex: number, array: JSONValue[]) => JSONValue, initialValue: JSONValue): JSONValue; <U>(callbackfn: (previousValue: U, currentValue: JSONValue, currentIndex: number, array: JSONValue[]) => U, initialValue: U): U; }
  ```

* reduceRight

  Calls the specified callback function for all the elements in an array, in descending order. The return value of the callback function is the accumulated result, and is provided as an argument in the next call to the callback function.

  ```ts
  { (callbackfn: (previousValue: JSONValue, currentValue: JSONValue, currentIndex: number, array: JSONValue[]) => JSONValue): JSONValue; (callbackfn: (previousValue: JSONValue, currentValue: JSONValue, currentIndex: number, array: JSONValue[]) => JSONValue, initialValue: JSONValue): JSONValue; <U>(callbackfn: (previousValue: U, currentValue: JSONValue, currentIndex: number, array: JSONValue[]) => U, initialValue: U): U; }
  ```

* reverse

  Reverses the elements in an array in place. This method mutates the array and returns a reference to the same array.

  ```ts
  () => JSONValue[]
  ```

* shift

  Removes the first element from an array and returns it. If the array is empty, undefined is returned and the array is not modified.

  ```ts
  () => JSONValue
  ```

* slice

  Returns a copy of a section of an array. For both start and end, a negative index can be used to indicate an offset from the end of the array. For example, -2 refers to the second to last element of the array.

  ```ts
  (start?: number, end?: number) => JSONValue[]
  ```

* some

  Determines whether the specified callback function returns true for any element of an array.

  ```ts
  (predicate: (value: JSONValue, index: number, array: JSONValue[]) => unknown, thisArg?: any) => boolean
  ```

* sort

  Sorts an array in place. This method mutates the array and returns a reference to the same array.

  ```ts
  (compareFn?: (a: JSONValue, b: JSONValue) => number) => JSONArray
  ```

* splice

  Removes elements from an array and, if necessary, inserts new elements in their place, returning the deleted elements.

  ```ts
  { (start: number, deleteCount?: number): JSONValue[]; (start: number, deleteCount: number, ...items: JSONValue[]): JSONValue[]; }
  ```

* toLocaleString

  Returns a string representation of an array. The elements are converted to string using their toLocaleString methods.

  ```ts
  () => string
  ```

* toString

  Returns a string representation of an array.

  ```ts
  () => string
  ```

* unshift

  Inserts new elements at the start of an array, and returns the new length of the array.

  ```ts
  (...items: JSONValue[]) => number
  ```

* values

  Returns an iterable of values in the array

  ```ts
  () => IterableIterator<JSONValue>
  ```
