Strict equality

Two values can be checked for strict equality. The result of such a comparison is either true, the two values are equal, or false, the two values are not equal. The operator for strict equality is ===.

let language = 'JavaScript';
let x = 10;
let c1 = language === 'Java';
let c2 = x === 10;
let c3 = x === '10';

The first comparison results in false, because language does not have the value 'Java'. So c1 is false. The second comparison results in true, because the value of x equals 10. So c2 is true. In the case of strict equality, it is also important that the two compared values have the same data type. c3 is false, because different data types are compared here. On the left side of the comparison is a number, on the right side a string.

Write a function equals that checks two values for strict equality.

Example: equals(1, 1) should return true and equals(1, 2) should return false.

+ Hint

function equals(a, b) {
  return ...
}

+ Solution

function equals(a, b) {
  return a === b;
}
