(Node.js) Transition from Crypt2.DecodeString to StringBuilder.Decode

Provides instructions for replacing deprecated DecodeString method calls with StringBuilder.Decode.

Note: This example requires Chilkat v11.0.0 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
