index: number,
array: this,
) => unknown,
thisArg?: any,
): number | undefined
#findLastIndex(
predicate: (
value: number,
index: number,
array: this,
) => unknown,
thisArg?: any,

#forEach(
callbackfn: (
value: number,
index: number,
array: this,
) => void,
thisArg?: any,
): void

Performs the specified action for each element in an array.

#includes(
searchElement: number,
fromIndex?: number,
): boolean

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

#indexOf(
searchElement: number,
fromIndex?: number,
): number

Returns the index of the first occurrence of a value in an array.

#join(separator?: string): string

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

#lastIndexOf(
searchElement: number,
fromIndex?: number,

#map(
callbackfn: (
value: number,
index: number,
array: this,
) => number,
thisArg?: any,
