Typescript in React Native

1. Define

Typescript is an open-source programming language developed and maintained by Microsoft. It is a strict syntactical superset of JavaScript, and adds optional static typing to the language.

2. Benefits of Typescript

a. Typescript supports many types

You can use class, interface, type, basic data types (number, string, Date, boolean, array,...).

b. Typescript helps us avoid many errors in run-time

Example: in javascript you have this function to subtract 100 for a number

function plusFive(num) {
  return num - 100;
}

The exception will be generated if I pass a string instead of a number, and this exception only happens at run-time, too dangerous.

c. Easy to read, test, expand and maintain

d. Easy to apply OOP principles, SOLID principles, Design Patterns

e. One of the biggest advantages of TypeScript is its code completion and IntelliSense. Intellisense provides active hints as a code is added.

f. The ability to compile down to a version of JavaScript that runs on all browsers
