JavaScript Int16Array from() Method Last Updated : 11 Jul, 2023 Comments Improve Suggest changes Like Article Like Report The Int16Array array represents an array of twos-complement of 16-bit signed integers. By default, the contents of Int16Array are initialized to 0. The Int16Array.from() function is used to create a new Int16Array from an array-like or iterable object. So when you want to convert an arrayLike or iterable object to Int16Array 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: Int16Array.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 Int16Array object.mapFn: This parameter is Optional which is a Map function to call on every element of the Int16Array.thisArg: This parameter is Optional which is a value to use as this when executing mapFn.Return Value:This method returns a new Int16Array instance. JavaScript programs to Illustrate the working of from() function: Example 1: In this example, we will see the basic use of the JavaScript Int16Array.from() method to create a new array from the string of numbers. javascript // Create a Int16Array from // a string like structure let array = Int16Array.from('654456543456'); // Display the result console.log(array); OutputInt16Array(12) [ 6, 5, 4, 4, 5, 6, 5, 4, 3, 4, 5, 6 ]Example 2: In this example, we will see the basic use of the JavaScript Int16Array.from() method implementing transformation to every element. javascript // Create a Int16Array from a array by converting // numbers twice the actual number let array = Int16Array.from([32, 43, 41, 34], z => z * 2); // Display the result console.log(array); OutputInt16Array(4) [ 64, 86, 82, 68 ]References: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/TypedArray/from# Comment More infoAdvertise with us Next Article JavaScript Int16Array from() Method A AmanSingh2210 Follow Improve Article Tags : JavaScript Web Technologies javascript-array JavaScript-Methods Similar Reads JavaScript Int8Array from() Method The Javascript Int8Array represents an array of twos-complement of 8-bit signed integers.
