  let str1= str.replace(/[A-Z]/g, function(v) {return ' '+ v.toLowerCase();
});
let arr=str1.split(/[\s,._]+/);

Try:

1. Split the string with regex . It will return an array
2. join the array with (’ - '). it will return a string
3. lower case the string

You can chain all of that method together

hope this help

happy coding
