Is there a way to locate the starting position of a specific portion within a string?

I am feeling exhausted right now and struggling to solve a simple problem.

The format of the string I have is as follows:

BROADCAST FROM x\ny\nz

Here, x represents a single word without any spaces or newlines, y is a number, and z is a string with a length of y characters.

All I need is to identify the starting index of z so that I can use string.slice(indexOfZ).

Could someone guide me on creating a regular expression in JavaScript for this purpose?

Perhaps it should look something like this...

pattern = /\n[0-9]{1,}\n.*/;
var index = string.match(pattern);

Do you see any mistakes in my approach?

Answer №1

What could be the reason why the regular expression /^BROADCAST FROM \w+ \d+ (.+)$/ is not functioning properly?

Answer №2

Using regular expressions can be useful, but in this particular case, it may be unnecessarily complicated.

let arrayParts = fullString.split("\n");

Update: It seems like all you need is the third element, so:

let z = arrayParts[2];

Answer №3

If you're looking to determine this, you can achieve it by breaking down the string using the forward slash (/).

var myString = x\ny\nz;
var str =  myString.split('\'); //assuming the format stays consistent.

var index = str[2].indexOf("z").

There might be alternative solutions available, but this is the one that popped into my head at the moment.

I trust that you find this information helpful.
