Stack Choices: JavaScript vs TypeScript
As a developer, there are many choices to make when building your next application. The rise of serverless technologies allows developers to build and run applications without thinking about servers and this also allows front-end developers to create full-stack applications and build SAAS web apps.
In Stack Choices, we take a closer look at some technologies that can help us to build these types of applications and try to make a good decision on what to use. This time, let’s take a look at going with plain old JavaScript or the rising star: TypeScript.

Besides that, it's one of the most loved languages, according to the 2019 Developer Survey by Stack Overflow.

You also get feedback while typing like flagging type-related errors as soon as they occur. This can help you write more maintainable code.
Although TypeScript is really good, it’s not perfect. In the beginning, I didn’t like working with TypeScript at all. It…
