Logical OR in JavaScript

The || operator is a logical OR and requires at least one condition to be met.

In the following example, if the variable num1 is greater than 0 or the variable num2 is greater than 0, then the condition will be true (it is enough at least one of the conditions to be met):

javascriptlet num1 = 10;
let num2 = -5;

if (num1 > 0 || num2 > 0) {
  console.log('+++'); // it will work
} else {
  console.log('---');
}
