var valid = WAValidator.validate('1KFzzGtDdnq5hrwxXGjwVnKzRbvf8WVxck', 'BTC');
if(valid)
	console.log('This is a valid address');
else
	console.log('Address INVALID');

// This will log 'This is a valid address' to the console.
var WAValidator = require('wallet-address-validator');

var valid = WAValidator.validate('1KFzzGtDdnq5hrwxXGjwVnKzRbvf8WVxck', 'litecoin', 'testnet');
if(valid)
      console.log('This is a valid address');
else
      console.log('Address INVALID');

// As this is a invalid litecoin address 'Address INVALID' will be logged to console.

Browser

<script src="wallet-address-validator.min.js"></script>
// WAValidator is exposed as a global (window.WAValidator)
var valid = WAValidator.validate('1KFzzGtDdnq5hrwxXGjwVnKzRbvf8WVxck', 'bitcoin');
if(valid)
    alert('This is a valid address');
else
    alert('Address INVALID');

// This should show a pop up with text 'This is a valid address'.
