Javascript/jQuery: Split camelcase string and add hyphen rather than space

Question

I would imagine this is a multiple part situation with regex, but how would you split a camelcase string at the capital letters turning them in to lowercase letters, and the

Answer 1

I don't know why all these solutions are so complex but i simply found this to be enough:

function camelCaseToDash(input){ 
     // replace Capital letter with the letter + a dash: '-', then lowercase everything.
     return input.replace(/([A-Z])/g, '-$1').toLowerCase(); 
}    

//or, using a callback function, directly lowercasing.
function camelCaseToDashCallback(input){
     //replace capital letter with lowercase variant + a dash '-'.
     return input.replace(/([A-Z])/g, (x)=> "-"+ x.toLowerCase());
}    

generally option 1 is faster though: https://jsfiddle.net/4557z/17/
