How to Parse a String with Comma Thousand Separators into a Number in JavaScript?

Parsing a String with a Comma Thousand Separator to a Number

When attempting to parse a string containing a comma as a thousand separator into a number, using parseFloat may not yield the expected result, as it treats the comma as a decimal point. To resolve this issue, consider the following solution:

Remove the commas from the string. JavaScript provides a convenient replace() method that allows you to search for a specific pattern (in this case, commas) and replace it with an empty string.

Here's an example:

let input = "2,299.00";
let output = parseFloat(input.replace(/,/g, ''));
console.log(output); // Output: 2299

By removing the commas, we convert the string into a valid numeric format that can be parsed using parseFloat.
