(Node.js) Base62 Encoding and Decoding

Demonstrates base62 encoding and decoding.

Note: This example requires Chilkat v11.2.0 or greater.

Install Chilkat for Node.js and Electron using npm at Chilkat npm packages for Node.js Chilkat npm packages for Electron on Windows, Linux, MacOS

    // Output: 
    // hello world --> AAwf93rvy4aWQVw

    // Base62 decode
    var sb = new chilkat.StringBuilder();
    sb.DecodeAndAppend("AAwf93rvy4aWQVw","base62","utf-8");
    console.log("decoded: " + sb.GetAsString());
