NodeJs - Remove multiple numbers and dots from a text file

I tried to remove numbers along with dots using nodejs

const replace = "1."
const replacer = new RegExp(replace, 'g', '')

function removeText() {
    let originalText = '
1. I can own unlimited wealth on this earth
2. My potential for wealth knows no bounds
3. I attract limitless financial opportunities
    ';
    
    let newText = originalText.replace(replacer, '');

    console.log(newText);
}

removeText();

using this code I can only remove "1." but what about 2., 3., I have this counting upto 100, can someone help me?

You can simply achieve this by just using digit RegEx.

Live Demo :

<!-- begin snippet: js hide: false console: true babel: false -->

<!-- language: lang-js -->

let originalText = `
1. I can own unlimited wealth on this earth
2. My potential for wealth knows no bounds
3. I attract limitless financial opportunities
`;

let newText = originalText.replace(/\d./g, '');

console.log(newText);

<!-- end snippet -->

split the string by lines. Filter out the empty values. Split each line by number followed by dot and finally join them back with new line.

let originalText = `
1. I can own unlimited wealth on this earth
2. My potential for wealth knows no bounds
3. I attract limitless financial opportunities
    `;

originalText=originalText.split('\n').filter(l=>l).map(line=>line.split(/\d+\.\s/)[1]).join('\n')

ChatGPT helped, To remove the line numbers (1., 2., and 3. Up to 100 and so on...) from the texts using only one function in Node.js, you can use the replace() function with a regular expression pattern. Here's an example:

const text = `
1. Test.
2. Test.
3. Test.
`;

const modifiedText = text.replace(/^\d+\. /gm, '');

console.log(modifiedText);

Output:

Test.
Test.
Test.

In the above code, we use the replace() function with a regular expression ^\d+\. to match any line starting with one or more digits followed by a dot and a space. The ^ represents the start of the line, \d+ matches one or more digits, \. matches the dot character, and the space after it matches a space character. The g flag is used for a global search, and the m flag is used for multiline matching.

By replacing the matched pattern with an empty string, we effectively remove the line numbers from the text. Have a nice day 😊
