TypeScript and 7 Things You Need to Know About it in 2021 | TypeScript vs Javascript | What is TypeScript

TypeScript’s popularity has been on a steady increase over the last few years and it’s one of the most promising programming languages coming into the new year.

With around 60% of JavaScript programmers making the switch to TypeScript, and another 20% more wanting to dip their feet in and try, let’s talk about what all the fuss is about.

If you were to make a Venn diagram, TypeScript would be the very big circle, with a smaller circle of JavaScript inside of it. Basically, TypeScript is a superset of plain Javascript, that adds static typing commands for use whenever you feel the need to.

Static typing helps with a whole heap of issues when navigating complex, large scale systems coded in JavaScript. It also makes refactoring code easy without breaking the system entirely and without running into hidden errors like the notorious “undefined is not a function”. Any programmers worth their salt have run into that one any number of times.

In fact, 15% of all JavaScript bugs can be detected with TypeScript. Dynamic typing can lead to bugs that can cause the server-side code to come grinding to a massive halt, but with TypeScript, the written aspect gives it a distinct edge when scaling up to the large code bases of commercial and business applications.
