How to know the Data Type of a variable
Sometimes beginner developers forget about the javascript data types, and in some situations, a developer needs to check the data type of a certain variable's value without searching on the internet.
There is an easy way in the js language itself which is the typeof
operator
let myVar = "I am ";
console.log(typeof myVar);
// output : string
let myNum = 14;
console.log(typeof myNum);
// output : number
let myAge = myVar + myNum;
console.log(typeof myAge);
// output : string
