The typedArray.forEach() is an inbuilt function in JavaScript which executes a given function once for each given typedArray element.
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.

Example:
javascript
// Constructing some typedArray const A = new Uint8Array([ 1, 3, 5, 7 ]) const B = new Uint8Array([ 2, 4, 6, 8 ]) // Calling callback function function callback(element, index, array) { console.log('a[' + index + '] = ' + element); } // Calling forEach() function A.forEach(callback); B.forEach(callback); |
