[Solved] consider a string which has question marks, numbers , letters [closed]


I leave the refactoring of regex on you, but this is something you can do using String.prototype.match.

function checkStr(str) {
	let match = str.match(/(\d)\?{3}(\d)/);
	return match && +match[1] + +match[2] === 10;
}

let out = checkStr('bdhfr6???3hfyrt5???eee5');
console.log(out)

out = checkStr('bdhfr6???4hfyrt5???eee5');
console.log(out)
