JSFoo Pune 2020

Optional Chaining and Null Coalescing are two amazing features that are to be shipped soon in JavaScript. The top errors that generally occur in a JavaScript codebase can be handled with these two upcoming features. They solve a complex error-handling problem that JS Developers face when working with variables and objects or references in general in the most effective manner. Although they are in the development stage, we can start using them already with our build tool plugins and the latest TS version. We will explore how useful these two features would be, the current status and How we can start using them already in our projects.

I will also go through the existing hacks developers follow and how it is going to change with these ES Next proposals.
