    In JavaScript, you can obtain the length of a string using the .length property. This property returns the number of characters in the string. Here's a simple example to illustrate this:

    let myString = "Hello, world!";
    let lengthOfString = myString.length;
    
    console.log(lengthOfString); // Output: 13
    

    In this example, myString is a string variable containing "Hello, world!". The expression myString.length computes the length of this string, which is 13 characters, including spaces and punctuation.

    This method is straightforward and is the standard way to get the length of a string in JavaScript. There are no alternative native methods for this specific task, as .length is the built-in and most efficient way to achieve this in JavaScript.
