Data types: Strings, Numbers, Booleans
Description
TypeScript infers data types on variables declared. It can be done like this;
Example 1: Strings
let name = 'Peace';
//TypeScript automatically infers the type of string on the name variable because the value is a string. If the value of the name variable is changed to a number or a different data type, an error will be produced.
Example 2: Numbers
let age = 3;
//TypeScript automatically infers the type of number on the age variable because the value is a number. If the value of the age variable is changed to a string or a different data type, an error will be produced.
Example 3: Boolean
let isLoggedIn = true;
//TypeScript automatically infers the type of boolean on the isLoggedIn variable because the value is a boolean. If the value of the isLoggedIn variable is changed to a number or a different data type, an error will be produced.
