if (typeof myVar === 'string'){
//I am indeed a string
}// Example 1:
const string = "Hello world!";
n = string.includes("world");
// n is equal to true in Example 1
// Example 2:
const string = "Hello world!, I am Kavyansh";
n = string.includes("I am Aman");
// n is equal to false in Example 2
// Note: the .includes method is case sensitiveif (typeof a_string === 'string') {
// this is a string

//If value is a string, it converts to integer.
//Otherwise it remains integer.
