useWindowSize hook in react Js is a simple and commonly used custom hook to get the window size at any given particular moment.

Customisable Toast Notification using JavaScript

2 Upvotes

I built a highly customisable toast notification using vanilla JavaScript that allows user to control the position, type (success or error), message content, and duration of display of the toast notification. I learnt a lot of important JavaScript concepts while building this project, and I highly recommend you to try it out as well. Here's a video explanation of building the project from scratch

Maps in detail | JavaScript

2 Upvotes

Many people get confused between when to use a map or an object in JavaScript. While I have seen many developers use objects usually, there are a lot many instances where maps would have been more suitable. So I decided to make a video explaining maps in detail, its differences between objects and when to use one over the other under 8 minutes.

How does this checkerboard code work

1 Upvotes

Hi, I am working on an exercise in a textbook and I am struggling to understand how the code works, the code produces a 8X8 checkerboard of alternating spaces and hashtags based on whether two loops starting at 0 and incremented by 1 per cycle is odd or even.

  1. x++ and y ++ mean to increase variable by 1 but use the original value so;

-1st Loop will be (x + y) = 0 + 0

-2nd Loop will be 1 + 1 3rd will be 2 + 2 etc - thus accounting for all even numbers and so printing " "

within the board = ""

But how is the code testing for odd numbers when they increment and are added together in such a way to only produce even numbers? How is the else activated?

If the code produces horizontal lines of alternating spaces and hashtags until it reaches up to 8 (board += "\n"), what part of the code is telling it to stop at 8 lines vertically?

``` let size = 8;

let board = "";

for (let y = 0; y < size; y++) {
for (let x = 0; x < size; x++) {
if ((x + y) % 2 == 0) {
board += " ";
} else {
board += "#";
}
}
board += "\n";
} ```

Problem with navbar

2 Upvotes

So I'm making this horizontal scrolling website, where the navbar is positioned horizontally as well.

The problem is that I cannot use window. addEventListener('scroll', function() {...} ). Instead, I have to use window.addEventListener('wheel'...) in order to hide the navbar.

The problem is that when the navbar hides after the scroll, it does not show up again. I tried fixing this, but still don't have a solution.

Is the problem with the event listener? Or is the problem with my code? Any help is appreciated. Thanks in advance.
