How to get Length of String in JavaScript ?

To get the length of a given string in JavaScript, you can use the length property of the string object.

In this example,

We create a string named str1 with a string value of "Hello World".
We then get the length of the string using the length property of the string object str1 and store the returned value in the length1 variable.
The length property returns the length of this string.
Finally, we print the value in length1 to the console using console.log().

// Length of "Hello World" String
let str1 = "Hello World";
let length1 = str1.length;
console.log(`Length of given string is: ${length1}`);

Length of given string is: 11

In this example,

We create a string named str2 with a string value of "apple".
We then get the length of the string using the length property of the string object str2 and store the returned value in the length2 variable.
The length property returns the length of this string.
Finally, we print the value in length2 to the console using console.log().

// Length of "apple" String

let length2 = str2.length;
console.log(`Length of given string is: ${length2}`);
