This is a project that I personally created to improve my understanding of Typescript. I will be adding to these consistently until I master Typescript!

TypeScript is a superset of Javascript. I uses the same doucumentation of JS. Its main goal is to be a staatic typechecker for Javascript programs. It tries to prevent users from having Data Type errors.

Number - a double-precision IEEE 754 floating point.

String - an immutable UTF-16 string.

BigInt - integers in the arbitrary precision format.

Boolean - true and false.

Symbol - a unique value usually used as a key.

Null - equivalent to the unit type.

Undefined - also equivalent to the unit type.

Object - similar to records.

There are also some other TS types to consider:

unknown - the top type.

never - the bottom type.

object literal - eg { property: Type }

void - for functions with no documented return value

T[] - mutable arrays, also written Array

[T, T] - tuples, which are fixed-length but mutable

(t: T) => U - functions
