An alternative implementation might be this. Not much in it but reads better than switch(true)...
const href = window.location.href;const findTerm = (term) => { if (href.includes(term)){ return href; }};switch (href) { case findTerm('google'): searchWithGoogle(); break; case findTerm('yahoo'): searchWithYahoo(); break; default: console.log('No search engine found');};
