The Difference Between Pass By Value & Pass By Reference in JavaScript

JavaScript is a programming language that gives our web applications and web pages the ability to think and act by making it interactive and dynamic. Like any other programming language, JavaScript offers us functions which are a set of defined commands or statements that are executed only when we call the function that has this code. The function takes an input or some arguments and returns the output. The input arguments can be passed by value or reference.

So, in this post, we’ll define the terms “pass by value” and “pass by reference” along with examples in JavaScript, as well as explain the differences between the two.

Is Java “pass by value” or “pass by reference” ?

Friends , in this article I’ll be explaining about whether Java uses pass by value or pass by reference ? After reading this article you will be able to grasp the concept about pass by value and pass by reference .While reading this article try to focus on example codes and associated comments .

Java is always pass by value and not pass by reference .

What does pass by value actually mean ?

As the name says , pass by value simply means , we pass the value of an Object and not actual/original reference variable of an Object from main function to the called function but the copy of reference variable of this object is passed to the called function which ultimately points to same object .

The essential JavaScript concepts that you should understand

Pass By Value vs Pass By Reference in JavaScript

If you are new to JavaScript, chances are you’ve already run into some of the funny behavior this language has to offer (exhibit A). At first, these weird quirks might seem ridiculous and frustrating, but I promise there is a method behind all of that madness.

One of the hardest hurdles to overcome, in my humble opinion, is the difference between passing by value vs passing by reference. _Why is this concept so tricky? _For starters, you can certainly get pretty far without really understanding how JavaScript interacts with primitive values and reference values. This can, and more often than not, will result in a ton of bugs that are hard to track down and annoying to fix. Secondly, this is a concept that WILL come up in technical interviews, so not understanding it will count as a huge red flag against you.
