How To Get Type Of Variable In Javascript?

Similarly, How do you check what type a variable is in JavaScript?

In JavaScript, the typeof operator is used to determine the type of an object or variable. The object type produced with the “new” keyword is also returned by the typeof operator. The typeof operator yields distinct types for a literal string and a string object, as seen in the above example.

Also, it is asked, How do you get typeof variables?

The built-in type() method in Python may be used to determine the type of a variable. Everything in Python is an object. As a result, when you use the type() method to output the type of a variable’s value to the console, it returns the object’s class type.
