this is a operation you can do in regex:

const testString1 = "I might contain the word StReAm and it might be capitalized any way.";
const testString2 = "I might contain the word steam and it might be capitalized any way.";
const re = /stream/i
console.log( !!(testString1.match(re) ));
console.log( !!(testString2.match(re) ))
