why not parse MATHJax symbol in JQuery when append symbol form object to DOM (HTML)

const ques=
[

{
que:" [x = {-b \pm \sqrt{b^2-4ac} \over 2a}.] ",
...................

margin and code awkward behavior

programmerabhi — Fri, 02 Oct 2020 17:10:43 +0000

What is happening here, it seems as if all the words are in a single line.

Because this is not the case with div etc.

This is happening only with the code tag

<!DOCTYPE html>

Page Title

<br>
.ex{<br>
border-left:5px solid green;<br>
}<br>
code{<br>
margin: 20px;</p>
<div class="highlight"><pre class="highlight plaintext"><code> }
</style>
</head>
<body>
<div class="ex">
<code>
what happens here <br>
whatever why not happening here <br>
whatever why not happening here <br>
whatever why not happening here <br>
whatever why not happening here <br>

&amp;lt;/code&amp;gt;
  &amp;lt;/div&amp;gt;

</body>
</code></pre></div>
<p></html></p>

Why does indexOf output like this?

programmerabhi — Sun, 09 Aug 2020 13:10:46 +0000

var num = [26, 16, 41, 32, 16, 28, 16, 41];
console.log(num.indexOf(41));// 2
console.log(num.indexOf(41, 2)); // 2
console.log(num.indexOf(16, -1)); // -1 why?
console.log(num.indexOf(16, -2)); // 6

lightweight syntax highlighter for javascript (for blogger)

Let someone have a lightweight code highlighter. The one that has been claimed that it is lightweight (Prism, Highlight, w3c, etc). I have tried all, there is no lightweight. If you have made your own or are in the project, please share if possible

function in an array , how to declare and access?

programmerabhi — Sat, 01 Aug 2020 08:15:38 +0000

var arr = [ function fun(){ console.log("this is a funtion ");} ];
console.log(arr0 );
output:

"this is a funtion "
undefined

To get the output "this is a function", how to access array.
And do not appear undefined in output
