### Fixes
- `[jest-config]` Simplify transform RegExp ([#10207](https://github.com/facebook/jest/pull/10207))
- `[jest-fake-timers]` Lazily instantiate mock timers ([#10551](https://github.com/facebook/jest/pull/10551))
- `[jest-runtime]` `require.main` is no longer `undefined` when using `jest.resetModules` ([#10626](https://github.com/facebook/jest/pull/10626))
- `[@jest/types]` Add missing values for `timers` ([#10632](https://github.com/facebook/jest/pull/10632))

### `transform` [object\<string, pathToTransformer | [pathToTransformer, object]>]
Default: `{"^.+\\.[jt]sx?$": "babel-jest"}`
Default: `{"\\.[jt]sx?$": "babel-jest"}`
A map from regular expressions to paths to transformers. A transformer is a module that provides a synchronous function for transforming source files. For example, if you wanted to be able to use a new language feature in your modules or tests that aren't yet supported by node, you might plug in one of many compilers that compile a future version of JavaScript to a current one. Example: see the [examples/typescript](https://github.com/facebook/jest/blob/master/examples/typescript/package.json#L16) example or the [webpack tutorial](Webpack.md).

_Note: a transformer is only run once per file unless the file has changed. During the development of a transformer it can be useful to run Jest with `--no-cache` to frequently [delete Jest's cache](Troubleshooting.md#caching-issues)._
_Note: when adding additional code transformers, this will overwrite the default config and `babel-jest` is no longer automatically loaded. If you want to use it to compile JavaScript or Typescript, it has to be explicitly defined by adding `{"^.+\\.[jt]sx?$": "babel-jest"}` to the transform property.
