Now that we've looked at the very basics of strings, let's move up a gear and start thinking about what useful operations we can do on strings with built-in methods, such as finding the length of a text string, joining and splitting strings, substituting one character in a string for another, and more.

Methods that modify the original array are known as mutator methods, and methods that return a new value or representation are known as accessor methods. 7) JavaScript String slice (beginIndex, endIndex) Method The JavaScript String slice (beginIndex, endIndex) method returns the parts of string from given beginIndex to endIndex.

This is where you define class members, such as methods or constructor. Strict mode The body of a class is executed in strict mode , i.e., code written here is subject to stricter syntax for increased performance, some otherwise silent errors will be thrown, and certain keywords are reserved for future versions of ECMAScript. For a shorter syntax when declaring methods on object literals, the shorthand method declaration is preferable. new Function way to declare functions normally should not be used.

In slice () method, beginIndex is inclusive and endIndex is exclusive. The call, apply and bind methods are NOT suitable for Arrow functions -- as they were designed to allow methods to execute within different scopes -- because Arrow functions establish "this" based on the scope the Arrow function is defined within.

It executes the given reducer function for each element of the array except empty values, resulting in a single output value. Here is how it looks like: Method chaining happens when you want to call multiple functions using the same object and its reference. In the above example, the array method map returns an Array , which has a formidable number of methods. JavaScript also provides some special methods and properties to every function object. So every function in JavaScript inherits those methods. Call, bind, and apply are some of the methods that every function inherits.

There are many useful built-in methods available for JavaScript developers to work with arrays. In this tutorial, we will use iteration methods to loop through arrays, perform function JavaScript automatically converts primitives to String objects, so that it's possible to use String object methods for primitive strings. In contexts where a method is to be invoked on a primitive string or a property lookup occurs, JavaScript will automatically wrap the string primitive and call the method or perform the property lookup. This is where you define class members, such as methods or constructor.
