If you want to check if a variable is a string, then use the typeof
operator.
The typeof
operator returns "string" if a variable is a string.
On the other hand, if a variable is not a string, then the typeof
operator returns a different value.
The syntax for using the typeof
operator with a string is
typeof string
Let's understand the process with the help of an example:
let x = "JavaScript"; if(typeof x === "string"){ console.log("Variable x is a string."); }else{ console.log("Variable x is not a string."); }
Output
Variable x is a string.
