atob javascript code example

Example 1: atob nodejs

(function () {
  "use strict";

  var atob = require('atob');
  var b64 = "SGVsbG8sIFdvcmxkIQ==";
  var bin = atob(b64);

  console.log(bin); // "Hello, World!"
}());

Example 2: atob javascript

The atob() and btoa() methods allow authors to transform content to and from the base64 encoding.

In these APIs, for mnemonic purposes, the "b" can be considered to stand for "binary", and the "a" for "ASCII". In practice, though, for primarily historical reasons, both the input and output of these functions are Unicode strings.
