In this article, we have put together different procedures for comparing strings in JavaScript. In this article, we divide the problem into three cases: The strict equality operator (===) checks if the two input operands are equal and then returns a Boolean result. In such situations, the Strict Equality Operator compares the strings. In case string1 comes before string 2 or if it is smaller than the invoked localeCompare() method, it will return -1 because b in bus comes before c in car in the alphabetical order.
