I have strings with extra whitespace characters. Each time there's more than one whitespace, I'd like it be only one. How can I do this using JavaScript?

Something like this:

const str = "  a  b     c  "
const result = str.replace(/\s+/g, ' ').trim()

console.log('result', result)
console.log('result.length', result.length)
