TypeScript is a programming language created by Microsoft that allows static typing. It provides a robust type system for JavaScript and allows it to be easier to read and debug. You can solve issues before even running the program. You can more easily refactor code and allow team members to orient themselves. Just by using TypeScript, you can solve a huge chunk of the bugs. This can be used for both frontend and backend work. This becomes very useful when working on large projects with a team. When working with an engineering team, team members would be able to work and help each other more effectively. You should use TypeScript because it's more reliable, explicit, and easy to use. If you have experience with JavaScript then TypeScript shouldn’t be very hard to transition to. You switch the extension from ‘.js’ to ‘.ts’. Of course, there are some huge things to get used to but it's a fun challenge I recommend. So join me as I teach you how to switch from JavaScrip to TypeScript. See you next week for Part 2!
