Function polyArrIncludes

polyArrIncludes<T>(
    theArray: ArrayLike<T>,
    searchElement: T,
    fromIndex?: number,
): boolean
The polyArrIncludes() method determines whether an array includes a certain value among its entries, returning true or false as appropriate. Note: The polyfill does not handle NaN correctly.
Type Parameters
- T
Parameters
- theArray: ArrayLike<T>
  The array or array like object of elements to be searched.
- searchElement: T
  The value to search for
- OptionalfromIndex: number
  The optional Zero-based index at which to start searching, converted to an integer.
  
  Negative index counts back from the end of the array — if fromIndex < 0, fromIndex + array.length is used. However, the array is still searched from front to back in this case.
  
  If fromIndex < -array.length or fromIndex is omitted, 0 is used, causing the entire array to be searched.
  
  If fromIndex >= array.length, the array is not searched and false is returned.
Returns boolean
A boolean value which is true if the value searchElement is found within the array (or the part of the array indicated by the index fromIndex, if specified).
