If I have a string in this format:
RED-MPWMC-40486655646-024
How can I extract MPWMC from this string with javascript?
No need of regex here. Just split it using - and access the array element with index=1.
var str = "RED-MPWMC-40486655646-024";
console.log(str.split("-")[1]);

I am trying to construct a regular expression in Javascript such that the string contains more b's than a's. Can contain other characters anywhere but b's have to be more than a's. Could anybody help?
Simplest route:
let moreAsThanBs = (str) => str.match(/a/ig).length > str.match(/b/ig).length;
console.log(moreAsThanBs("Are there more As than Bs in this sentence?"));
console.log(moreAsThanBs("Are there more As than BBBBBs in this sentence?"));

I am trying to understand what it means when a code appears in between the brackets. I know that has something to do with an array.
In the case of "inputArray[0]", it is finding the value at index position 0 (the first element) in the array "inputArray".

I want to write a regex for matching *#xxx[.]gr in js.
My regex so far :
/^(([^<>()\[\]\\.,;:\s#"]+(\.[^<>()\[\]\\.,;:\s#"]+)*)|(".+"))#((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/
I want : *#xxx.gr
If I understand your specs correctly this should suit you:
/^[^<>()\[\]\\.,;:\s#"]+#[^<>()\[\]\\.,;:\s#"]{3}\[\.\][^<>()\[\]\\.,;:\s#"]{2}$/g
