I have a kebabize function which converts camelCase to kebab-case. I am sharing my code. Can it be more optimized? I know this problem can be solved using regex. But, I want to do it without using regex.

const kebabize = str => {



    let subs = []

    let char = ''

    let j = 0



    for( let i = 0; i < str.length; i++ ) {



        char = str[i]



        if(str[i] === char.toUpperCase()) {

            subs.push(str.slice(j, i))

            j = i

        }



        if(i == str.length - 1) {

            subs.push(str.slice(j, str.length))

        }

    }



    return subs.map(el => (el.charAt(0).toLowerCase() + el.substr(1, el.length))).join('-')

}



kebabize('myNameIsStack')
