How to check if strings are rotations of each other in JavaScript

Answer 1

function rotations(str1, str2) {
	if (str1.length != str2.length)
    	return false;
        
	console.log(str1 + str1);
    
    return (str1 + str1).indexOf(str2) != -1;
}
     

const str1 = "abcxd";
const str2 = "cxdab";
 
if (rotations(str1, str2))
    console.log("yes");
else
    console.log("no");
