TypeScript 5.7: Better Inference, Better DX
TypeScript 5.7 focuses on developer experience improvements.

Improved Type Inference

The compiler is now smarter about inferring types in complex scenarios, reducing the need for explicit annotations.

## Better Error Messages

Error messages now include more context and suggestions for fixes:

error TS2345: Argument of type 'string' is not assignable to parameter of type 'number'.

Did you mean to use parseInt()?

## Performance

Faster incremental builds

Reduced memory usage

Improved editor responsiveness

TypeScript keeps getting better with every release.

Note

Before upgrading, we recommend reviewing the breaking changes in the official documentation.
