In this article we are going to discuss about Pass by value and Pass By Reference in Javascript Programming as we already know about function and various ways to invoke them. The primitive data types; i.e., Number, Boolean, String etc., are all pass by values, but Objects can be both...
JavaScript is often described as a "pass-by-value" language, but this can sometimes be a bit misleading. The behavior of passing values to functions in JavaScript is more accurately described as "pass-by-sharing" or "pass-by-reference for objects, but pass-by-value for primitives." Let's...
A very detailed explanation about copying, passing and comparing by value and by reference is inthis chapterof the"JavaScript: The Definitive Guide"book. Before we leave the topic of manipulating objects and arrays by reference, we need to clear up a point of nomenclature. The phrase "pass by...

On this page, we will look into pass-by-reference and pass-by-value. Let’s explore their differences and find out what language JavaScript is considered.

In Java, arguments are passed to methods by value. This means that when you pass an argument to a method, the method receives a copy of the argument rather than a reference to the original object.
