Extract decimal fron string regex

const regex = /[0-9][+-]?[0-9]{1,3}(?:,?[0-9]{3})*(?:\.[0-9]{2})?/g;

// Alternative syntax using RegExp constructor
// const regex = new RegExp('[0-9][+-]?[0-9]{1,3}(?:,?[0-9]{3})*(?:\\.[0-9]{2})?', 'g')

const str = `\$20,000.00 USD`;
let m;

while ((m = regex.exec(str)) !== null) {
    // This is necessary to avoid infinite loops with zero-width matches
    if (m.index === regex.lastIndex) {
        regex.lastIndex++;
    }

    // The result can be accessed through the `m`-variable.
    m.forEach((match, groupIndex) => {
        console.log(`Found match, group ${groupIndex}: ${match}`);
    });
}
