JavaScript: How to get the type of a variable in JS?

Just use the typeof operator to get the type of a variable. Here is how to use it:

  1. let variable = "webdevetc";
  2. console.log(typeof variable)

string

N.B. if you do typeof on a variable that is set to null, it will tell you it is an object.
