I am trying to convert sSlack mention markup to custom string so I can use it for better presentation.
Example input: #[user a name ](12345) (hi) #[user b name](67890)
Required output: <#12345> (hi) <#67890>
I have tried input.replaceAll(/#\[(.*?)\]\(.*?\)/g, "<#$1>"), but this prints the user name and not ID.

What does the -> operator do in the .js code below?
_blm.mpU_onIdentified(function() {
console.log('find_program_result.js -> mpU_onIdentified');
_blm.mpU.people.set({
'findProgramsResultsHref': location.href
});

This isn't an operator - it's inside a string which is being logged. You can identify it by the quotes enclosing it:
console.log('find_program_result.js -> mpU_onIdentified');
// quotes --^------------------------------------------^

Below is the code I currently using which I need to round the end result to 2 decimals.Can someone help me figure out what I did wrong.
total = panjang*ht+hf;
document.getElementById("ototal").innerHTML =eval(total(toFixed(2)));

The variable total is a number, not a function.
You should use toFixed function like this
total.toFixed(2)

I have this string
24.733835, 121.34365500000001:AP-54184
i want to spilt the string by ':' , but why can't spilt the string
var newarray= '24.733835, 121.34365500000001:AP-54184'.spilt(/:/);
document.write(newarray[0]+","+newarray[1]+"<br>");
Is there anything wrong with my code ?

There is no function spilt() unless it's part of the Milk class. You want split(':')

You have a typo in your code, it should be .split(), not .spilt()...

I have stumbled across this code:
"".length
It should obviously return 0, but for some reason returns 1337. Is this some kind of trick i dont know?

The code is:
Open quote
Unicode Character 'ACTIVATE ARABIC FORM SHAPING' (U+206D) ×1337
Close quote
.length
Since the string is made of 1337 "invisible" characters, the length is 1337.

$("td[id^='td0_']")
My question is how can I replace 0 in the example above with a variable myvar?

You should be able to use:
$("td[id^='td" + myvar + "_']")

Use the quotes appropriately.
$("td[id^='td" + myvar +"_']")
