Syntax:
typedarray.forEach(callback)
Parameter: It accepts a parameter “callback” function which produces each element of the new typedArray and this function takes three parameters that are specified below-
- currentValue: It is the value of the current element which is being processed in the typedArray.
- index: It is the index of the current element being processed in the array.
- array: It is the array on which the forEach() function is being called.

function callback(element, index, array) {
console.log( 'a[' + index + '] = ' + element);
}
