find the length of a string in javascript

To find the length of a string in JavaScript, you can use the length property of the string object. Here's an example:

index.tsx
let myString = "Hello, World!";
let stringLength = myString.length;
console.log(stringLength); // Output: 13
109 chars
4 lines

In this example, we create a string variable myString and assign it the value "Hello, World!". We then use the length property to find the length of the string and store it in the stringLength variable. Finally, we use console.log() to output the value of stringLength, which is 13.
