removeEventListener not working.

Morris John — Thu, 10 Dec 2020 09:11:28 +0000

I don't seem to understand why I can't remove the event listener where I added a text through insertAdjacentText when clicked. I really hope someone helps me. I've gone through hours trying to debug it.

const header = document.querySelector(`header h1`);
const button = document.querySelector(`header button`);

function addText() {
   header.insertAdjacentText(`afterend`, `Yeah`);
   console.log(`yeah`);
}

header.addEventListener(`click`, addText);
button.removeEventListener(`click`, addText);

I'm trying to write the same code in two different computers using VS Code

I'm trying to work on my code every chance I've got. Is it possible to work on the same code using VsCode with two different computers?
If it's possible, what extension would I need?

How do I get the first/last char of a string from a user input (input.value)

Morris John — Thu, 14 May 2020 09:23:44 +0000

So I'm trying to build this project where I ask the user to enter their name, then I display said name in full and put the initials in a button instead of "player one". I don't know why but slice(-1), charAt(str.length -1) are not working.

<div>
        <label for="name">Enter your name</label>
        <input type="text" name="" id="yn">
        <button class="submit">Submit</button>
    </div>
    <p class="welcome"></p>

var yourname = document.querySelector("#yn");
var welcome = document.querySelector(".welcome");
var div = document.querySelector("div");
var submit = document.querySelector(".submit");

submit.addEventListener("click", function(){
    div.classList.add("hide");
    welcome.textContent = "Welcome " + yourName.value
})

Thanks

Is it possible to nest an array in a JavaScript object?

Morris John — Sat, 25 Apr 2020 05:25:27 +0000

So I've gotten to JavaScript objects and it's very cool. Almost cooler than arrays but I've got an issue. I know it's possible to nest objects in arrays and I've done them but I can't seem to do it the other way round.

I've googled this and I haven't gotten a satisfactory response.

Thanks.

Why should one use multiple Variables when you could store everything in an array?

Morris John — Thu, 02 Apr 2020 19:11:34 +0000

So I just started learning JavaScript (using Angela Yu's Udemy course) and I'm presently learning arrays. So I'd like to know why one would use variables when you could store all the data you need in one array and use the .push to always add since it looks as though JavaScript doesn't have size limit for arrays.

Thanks

Need for a mentor

Morris John — Sat, 23 Nov 2019 12:44:52 +0000

I'm currently learning HTML, CSS & eventually JS.

HTML seems fairly easy but CSS has been the kicker. Positioning especially.

Anywho, I'm currently looking for a mentor to guide me through or someone to "ginger" me when I'm down.

*I'm currently taking Colt Steele's course on Udemy.

"Ginger" in this context is a Nigerian slang meaning motivate.

Thanks, Dev community
