Decodes a string of data which has been encoded using base-64 encoding.

  • Create a Buffer for the given string with base-64 encoding.
  • Use Buffer.prototype.toString() to return the decoded string.
const atob = str => Buffer.from(str, 'base64').toString('binary');
atob('Zm9vYmFy'); // 'foobar'
