[TypeScript](https://www.typescriptlang.org/) is a language for application-scale JavaScript. TypeScript adds optional types to JavaScript that support tools for large-scale JavaScript applications for any browser, for any host, on any OS. TypeScript compiles to readable, standards-based JavaScript. Try it out at the [playground](https://www.typescriptlang.org/play/), and stay up to date via [our blog](https://blogs.msdn.microsoft.com/typescript) and [Twitter account](https://twitter.com/typescript).

## Contribute
|
|
|
|
**NOTE: Code changes in this repo are now limited to a small category of fixes**:
|
|
|
|
* Crashes that were introduced in 5.9 or 6.0 that *also* repro in 7.0 *and* have a portable fix *and* don't incur other behavioral changes
|
|
* Security issues
|
|
* Language service crashes that substantially impact mainline usage
|
|
* Serious regressions from 5.9 (these must *seriously* impact a *large* proportion of users)
|
|
|
|
Most bug fixes should be submitted to the [typescript-go](https://github.com/microsoft/TypeScript-go) repository.
|
|
Feature additions and behavorial changes are currently on pause until TypeScript 7.0 is completed.
