For now, `JavaScript` does not support any `data structure`. If developers want to use `data structure`, they can only rely on community (eg. `github`). This is very bad.

The reasons are as follows:

1. The `data structure` belongs to the basic function and has a wide range of application scenarios. It needs the support of the engine (eg. `V8`) to make it play faster, rather than using `js` to write it.

2. Most developers will only choose the library by `github star` and have no time to see whether its implementation is correct and **efficient**.

I think we should gradually improve the proposal in this regard. His importance doesn't even need my explanation.

Let's start with the priority queue !!! Of course, the more `data structure` supported, the better.

Hi @ttttttssssss

Were you imagining something similar to [heap - npm](https://www.npmjs.com/package/heap) ? Which is inspired by Python's [heapq](https://docs.python.org/3/library/heapq.html).

Yes. `Heap` and `Priority Queue` are one thing in principle.

So what do you think of the `priority queue`(`heap`) as a proposal?

I'm curious that no one commented on my posts. Is it because it's not attractive enough?

As far as I know, `Java`, `Python`, `C++`, `Go` are all supported, but `JS` gives it to the community library.

What are the use cases for it? What would an engine be able to do that a userland implementation couldn’t?

If python, java and c++ has built-in priority queue then why can't we have it with JavaScript ?
