Type inference is the automatic detection of the data type of an expression in a programming language. This feature is present in some strongly statically typed languages, including TypeScript.

Type Inference is one of the most important concepts to master in TypeScript. The official TypeScript documentation doesn’t provide in-depth information about type inferences nor how and why to use it.

Types could be implicit and explicit. Implicit typing removes the need of writing the types and lets the TypeScript compiler reason about the types of variables and expressions.
