# TypeScript

Tool · [Standard tools and platforms](https://ecosystem.samcarlton.com/tools)

Also called: TS, Type Script

[JavaScript](https://ecosystem.samcarlton.com/javascript) with types added. [Developers](https://ecosystem.samcarlton.com/software-engineer) state what kind of data each value holds, and mistakes are caught before the code runs. [Microsoft](https://ecosystem.samcarlton.com/microsoft) maintains it.

**For example:** A [developer](https://ecosystem.samcarlton.com/software-engineer) moves a growing project to TypeScript so a renamed field shows errors everywhere it is still used.
