How to convert a camel-case string to dashes in JavaScript?

To convert a camel-case string to dashes in JavaScript, we can use the string’s replace method.

For instance, we write:

const camel = 'fooBar'
const dashed = camel.replace(/[A-Z]/g, m => "-" + m.toLowerCase());
console.log(dashed)

to call camel.replace with a regex to match all capital letters.

And then we pass in a callback that replace the matches with a dash and the matched letter converted to lower case concatenated to it.

As a result, dashed is "foo-bar".
