String equality in JavaScript

When using the if construct, strings can also be compared. For example, let the variable test store some string, for example 'abc':

let test = 'abc';

Let's check if the content of the variable test is equal to the string 'abc':

let test = 'abc';

if (test == 'abc') {
	console.log('+++'); // it will work
} else {
	console.log('---');
}

Given the variables test1 and test2 containing strings. Check if their values are equal and display the corresponding message.
