indexOf() method returns the first index at which a
given element can be found in the typed array, or -1 if it is not present. This method
has the same algorithm as
is one of the typed
array types here.

typedarray.indexOf(searchElement[, fromIndex = 0])
- Element to locate in the typed array.
- The index to start the search at. If the index is greater than or equal to the typed array's length, -1 is returned, which means the typed array will not be searched. If the provided index value is a negative number, it is taken as the offset from the end of the typed array. Note: if the provided index is negative, the typed array is still searched from front to back. If the calculated index is less than 0, then the whole typed array will be searched. Default: 0 (entire typed array is searched).
The first index of the element in the array;
-1 if not found.
searchElement to elements of the
typed array using strict
equality (the same method used by the ===, or triple-equals, operator).
var uint8 = new Uint8Array([2, 5, 9]); uint8.indexOf(2); // 0 uint8.indexOf(7); // -1 uint8.indexOf(9, 2); // 2 uint8.indexOf(2, -1); // -1 uint8.indexOf(2, -3); // 0
