Strings and numbers equality in JavaScript

As you know, a number in quotes is a string. For example, '3' is a string. However, when comparing such strings with real numbers, JavaScript considers the quoted string to be equal to the same number.

For example, let's compare the string '3' and the number 3:

javascriptif ('3' == 3) {
  console.log('+++'); // it will work
} else {
  console.log('---');
}

javascriptlet test1 = '123';
let test2 = 123;
