Tips for extracting the text either before or after a certain character within a string

Consider the following two strings:

  var str = "Extract Me @ Leave Me";
  var str2 = "Not This @ Yes, This";

Imagine a function named extractString() that can work like this:

 extractString("frontOf", "@", str); // => Extract Me
 extractString("behindOf", "@", str2); // => Yes, This

Or if you prefer:

 extractString("frontof @", str); // => Extract Me
 extractString("behindof @", str2); // => Yes, This

How would you implement the extractString() function? Can you create it for me?

Answer №1

To address the simple scenario you presented, my approach would involve utilizing the standard string split function:

var str = "Don't Grab Me @ Nope Claim Me";
var sections = str.split(/\s*@\s*/);
var firstSection = sections[0];
var secondSection = sections[1];
console.log("first part: " + firstSection);
console.log("second part: " + secondSection);
