cryptojs WordArray usage

cryptojs_wordarray.js

/**
 * cryptojs use WordArray (CryptoJS.lib.WordArray) as parameter/result frequently.
 *    A WordArray object represents an array of 32-bit words. When you pass a string,
 * it's automatically converted to a WordArray encoded as UTF-8.
 */

var CryptoJS = require("crypto-js");

// convert String to WordArray
var wordArray = CryptoJS.enc.Utf8.parse('Hello, World!');

// convert WordArray To String
var result1=wordArray.toString(CryptoJS.enc.Utf8);
var result2=CryptoJS.enc.Utf8.stringify(wordArray);

console.log(result1);
console.log(result1===result2);

Hi, I've a question about how can I do this following PHP Code

$signStr = base64_encode(hash_hmac('SHA1', 'msg', $secret_key, true).'msg');

into JS?

CryptoJS.enc.Base64.stringify(CryptoJS.HmacSHA1('msg', secret_key) + 'msg') ;

It's not work and throw error
crypto-js.js:789 Uncaught TypeError: wordArray.clamp is not a function

Base64.stringify wants a wordArray as the input, not a string. Do that conversion first.
