JavaScript Int8Array from() Method Last Updated : 26 May, 2023 Comments Improve Suggest changes Like Article Like Report The Javascript Int8Array represents an array of twos-complement of 8-bit signed integers. By default, the contents of Int8Array are initialized to 0. from the () function of Int8Array used to create a new Int8Array from an array-like or iterable object. So when you want to convert an arrayLike or iterable object to Int8Array then you can use this function by passing the object as a parameter to this function along with the map function and value used for the map function if needed. Syntax: Int8Array.from(source[, mapFn[, thisArg]]) Parameters: This method accepts three parameters that are specified below- source: This parameter is an array-like or iterable object which is used to convert to an Int8Array object.mapFn: This parameter is Optional which is a Map function to call on every element of the Int8Array .thisArg: This parameter is Optional which is a value to use as this when executing mapFn. Return Value: This method returns a new Int8Array instance. JavaScript examples to Illustrate the working of from() function: Example 1: In this example, we will see the use of JavaScript Int8Array from() Method. javascript //create a Int8Array from a string like structure let array = Int8Array.from('876543456789'); //print the result console.log(array); Output: 8, 7, 6, 5, 4, 3, 4, 5, 6, 7, 8, 9 Example 2: In this example, we will add one to every element of the array using the JavaScript Int8Array from() Method. javascript //create a Int8Array from a array by //adding 1 to each number using function let array = Int8Array.from([9, 2, 1, 4, 3], z => z + 1); //print the result console.log(array); Output: 10, 3, 2, 5, 4 We have a complete list of Javascript Array methods, to check those please go through this Javascript Array Complete reference article.
