Best Practices

First:

function pigIt(str){
  return str.replace(/(\w)(\w*)(\s|$)/g, "\$2\$1ay\$3")
}

Second:

pigIt = s => s.split(' ').map(e => e.substr(1) + e[0] + 'ay').join(' ');

My solutions

function pigIt(str){
  //Code here
  str = str.trim().split(/\s{1,}/);
    return str.map(val => {
        if (/^[A-Za-z]+$/.test(val)) {
            return `${val.slice(1)}${val.slice(0, 1)}ay`;
        }
        return val;
    }).join(' ');
}
