To know the type of the value/variable, we can use the typeof operator

Primitive Types

  • String

A string is represented by the series of characters enclosed by double/single quotes

const name = "SnowBit"
const favLang = "JavaScript"
  • Integer

It represents a number that can be written with or without a decimal

const age = 18
const price = 24.02
  • Boolean

It is a logical entity that has only two values: true and false, basically, booleans are used for conditional operations

const access = true
const isAdmin = false
  • Undefined

When a variable is declared but not assigned, the value of that variable is undefined

  • Null

It represents invalid or non-existent value

const api = null

Thank you for reading, have a nice day!
