Steps to extract the string into a separate variable upon successfully matching the specified regular expression in JavaScript

Imagine you have a string like this:

const message = 'This is a relationship: Salary = 73010 - 58.9 * Potential'

Your goal is to extract everything after relationship: and store it in a new variable using Regex. You also want to update the original variable so that it only contains:

message = 'This is a relationship'

Here's what you've come up with so far:

const equation = new RegExp(/relationship:.*$/); // This captures everything starting from 'relationship:'
const tooltip = message.split(equation);
const tip = message.replace(equation, '');

Don't worry about being a beginner with your code. We all start somewhere, and learning Regex can be tricky at first!

Answer №1

Can we assume that the pattern is always located after the colon :? If so, this process can be simplified without the need for a specific regex:

let input = 'This is a story : Plot twists in every chapter';

const parts = input.split(":");

input = parts[0].trim(); // Update the original input
const details = parts[1].trim();

console.log(`Story: "${ input }"`);
console.log(`Details: "${ details }"`);
.as-console-wrapper { min-height: 100%!important; top: 0; }

The result will be:

Story: "This is a story"
Details: "Plot twists in every chapter"
