Pass by Value vs Pass by Reference in Javascript

In this article, I will be discussing the difference between pass by value and pass by reference.

In javascript, things are either mutable or immutable.

Hm…I know a lot of people don’t understand what that means. Let’s come up with an example:

const a = 4;
let b = a;
b = 5;
console.log(a); // will print out 4

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 .

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.

Java Vs. JavaScript: Know the Difference

What a mess it could be to share the same name — especially if you are a programming language. Even if you are already over 20 years old, IT newbies periodically confuse you with your namesake. This happens all the time with Java and JavaScript, although they are not related at all! As someone on the internet said. They correlate in much the same way as a car and a carpet.

Why do these two languages have such similar names? How do they differ from each other, and what else do they have in common? This article will provide the answers to these questions.
