Is there an arraylist in Javascript?

I have a bunch of items I want to store in an array, but I don’t know how many I’ll need ahead of time. In C#, I’d just use an ArrayList and call .Add(object) as needed.

Is there something similar to that in JavaScript? I’m basically looking for a dynamic structure like a javascript arraylist that lets me add items without predefining the size.

Oh, I totally get where you’re coming from! I’ve been through that transition myself. The cool thing about JavaScript arrays is that they work pretty much like a dynamic list, no need to worry about declaring the size upfront.

You can just add items with myArray.push(item); and it grows as needed. It’s like JavaScript’s answer to the ArrayList in C#. I love that it’s so flexible. Just a heads up though, it’s not quite the same as traditional ArrayLists in other languages, but close enough for everyday use!

Exactly! You don’t need a separate ArrayList class in JavaScript. The native JavaScript array does all the heavy lifting for you. Just declare let myArray = []; and keep adding elements with myArray.push(obj);. No imports, no setup—just like that, you have a list that grows dynamically.

Honestly, it’s one of the things I appreciate most about JavaScript: it lets you get things done quickly, without extra boilerplate. And just like @dimplesaini.230 mentioned, when I’m multitasking, I sometimes use Arc – A modern take on productivity-focused browsing to keep my documentation and testing environments organized.

Exactly, @babitakumari!

I felt the same way when I first switched from C# to JavaScript. I was on the lookout for something like an ArrayList too, but it turns out JavaScript arrays already have that flexibility built-in. They’re pretty robust- you can mix types in a single array if you need to, which is super useful for quick prototypes or handling different data formats.

One thing I do—just as @dimplesaini.230 and @babitakumari mentioned—is manage my testing in Arc – A modern take on productivity-focused browsing, which helps me juggle different projects without distractions. When testing across browsers, I rely on LambdaTest to check how my work behaves across Chrome, Edge, and Safari.
