What is Typescript?
Typescript utilizes static type definitions, meaning that you can be as specific with your objects as you’d like, either by referencing other objects or using primitives. Many people stray away from Typescript due to the extra steps required to make it work, however the standard belief is that those steps are worth implementing to combat the potential debugging time suck.
Popularity for Typescript is growing, and a majority of job listings include JS or TS as accepted languages. Most companies that utilize JS as one of their main languages will use TS, as well. It should come as no surprise that it’s used by Microsoft, but other large names like Bloomberg, JP Morgan, and Salesforce include TS in their tech stack, as well.
- Works well with larger applications
- Bugs are spotted early: about 15 percent of bugs are found in the compiling stage
- Easier to read and understand
- Can have a steep learning curve if no prior knowledge of JS
- Adds an extra step to writing code
- Not as large of a community, so there’s less of an opportunity to collaborate or bounce off ideas
So… which one should you use?
If you are working on a smaller application, JS should be enough. However, the larger your application gets and the more data you have, TS can be more beneficial.
