Fresh releases of Visual Studio 2017 for Mac and TypeScript 3.2

Microsoft released fresh version of Visual Studio 2017 for Mac and TypeScript 3.2. Let’s have a quick look at these releases.

TypeScript 3.2

TypeScript 3.2 release is here.

TypeScript is a language that brings static type-checking to JavaScript, so that you can catch issues before you run your code or even before you save your file.

The benefit of any strongly typed languages is that, you can type-safely deal with variables. For example, if you try to add a number and a text string would cause a strongly typed compiler to show up an error, but in vanilla JavaScript would just spit out a string, which may not have been the intent.

These are the new features of TypeScript 3.2.

  • TypeScript 3.2 introduces support for large integers via the primitive type bigint. Now, TypeScript will warn you, if you try to mix number and bigint types.
  • TypeScript 3.2 introduces stricter checking for bind, call, and apply.
  • TypeScript 3.2 can now produces suggestions for most of the variables and parameters that would have been reported as having implicit any types and a quick fix to automatically infer the type.
  • Now, in TypeScript 3.2, some parameters no longer accept null, or accept something a bit more specific based on the type.
  • Improving formatting, TypeScript 3.2 can now smartly format several different constructs.
  • wheelDeltaX, wheelDelta, and wheelDeltaZ have all been removed in TypeScript 3.2, as they are deprecated properties on WheelEvents.
