With apply(), you can assign an arbitrary value as this when calling an existing function, without first attaching the function to the object as a property. This allows you to use methods of one object as generic utility functions.
The Difference Between call () and apply () The call() method takes arguments separately. The apply() method takes arguments as an array. The apply () method is very handy if you want to use an array instead of an argument list.
JavaScript provides the call (), apply (), and bind () methods for setting the this context within a function. These methods are especially useful when working with object-oriented code or handling different function contexts.
In this article, I am going to explain how to use call, apply, and bind in JavaScript with simple examples. We will also implement an example that showcases how you can create your own map function with the apply function.
The apply () method in JavaScript is used to call a function with a given this value and an array (or array-like object) of arguments. It’s similar to the call () method, but while call () passes arguments individually, apply () takes an array of arguments.
In this tutorial, you will learn about the JavaScript Function apply () method with the help of examples. In this article, you will learn about the apply () method of Function with the help of examples.
Struggling with .call (), .apply (), and .bind () in JavaScript? This practical guide breaks down how they work, real-world use cases, and performance tips — with simple examples and developer insights.
In JavaScript strict mode, if the first argument of the apply() method is not an object, it becomes the owner (object) of the invoked function. In "non-strict" mode, it becomes the global object.
