/**
|
|
* Finds the index of the first occurrence of a value in an array.
|
|
*
|
|
* This method is similar to `Array.prototype.indexOf`, but it also finds `NaN` values.
|
|
* It uses strict equality (`===`) to compare elements.
|
|
*
|
|
* @template T - The type of elements in the array.
|
|
* @param array - The array to search.
|
|
* @param searchElement - The value to search for.
|
|
* @param [fromIndex] - The index to start the search at.
|
|
* @returns The index (zero-based) of the first occurrence of the value in the array, or `-1` if the value is not found.
|
|
*
|
|
* @example
|
|
* const array = [1, 2, 3, NaN];
|
|
* indexOf(array, 3); // => 2
|
|
* indexOf(array, NaN); // => 3
