What is "typeof" operator in JavaScript

#javascript #node #webdev

typeof operator determines the type of the input

For example,

console.log(typeof 9.8)
Enter fullscreen mode Exit fullscreen mode

The output will be - "number"

console.log(typeof "Gravitational acceleration of Earth is 9.8ms^-2")
Enter fullscreen mode Exit fullscreen mode

The output will be - "string"

console.log(typeof true)
Enter fullscreen mode Exit fullscreen mode

The output will be - boolean

Thank you for reading, have a nice day!
