Tips, Tricks, and Techniques for Node.js Development 2.4: Optional Catch Binding

The video tutorial introduces the optional catch binding feature in ECMAScript, explaining its proposal process through TC39 and its implementation in Node.js. It highlights the use of Node.green to check feature support across different Node.js versions. The tutorial also covers the use of instance class fields with the Harmony flag, emphasizing the experimental nature of these features. The video concludes with a brief overview of ECMAScript features and a preview of the next section on writing asynchronous code.

Explain the role of TC39 in the development of ECMAScript features.
