Comparison

Comparing values

Goal

Understand that a comparison always returns true or false.

Explanation

  • Comparison means checking two values against each other.
  • JavaScript can test whether values are equal, different, greater, or less.
  • The result of a comparison is always a boolean: true or false.
  • If the condition is correct, the result is true.
  • If the condition is wrong, the result is false.

Analogy

A comparison is like a yes-or-no question. JavaScript looks at two values and answers true or false.

Code

console.log(5 === 5);
console.log(5 === 10);

Result: true false

Common mistake

Beginners sometimes expect a comparison to return the value itself. In reality, it returns only true or false.

Remember

  • ✦ A comparison returns a boolean.
  • ✦ true means the check passed.
  • ✦ false means the check failed.
