- The first operator we explore is the Equal to (
==
) operator. It checks if two values are equal. For example:
const priceOne = 5;
const priceTwo = 10;
console.log(priceOne == priceTwo);
Here, we used the Equal to (
==
) operator to check if the values of priceOne and priceTwo are equal.Comparison operators always return a boolean value. In this case we got
false
because priceOne and priceTwo are not equal.Now, priceOne and priceTwo have the same value.
const priceOne = 10; const priceTwo = 10; console.log(priceOne == priceTwo);
The second operator we explore is the Not Equal to (
!=
) operator. It checks if two values are not equal. For example:const priceOne = 5; const priceTwo = 10; console.log(priceOne != priceTwo);
- Now, we got
true
because priceOne and priceTwo are indeed not equal.
- Now, we got
Let's look at other types of comparison operators.
The Greater than (
>
) operator checks if the left value is greater than the right value. For example:
const priceOne = 5;
const priceTwo = 10;
console.log(priceOne > priceTwo);
console.log(priceTwo > priceOne);
- The Less than (
<
) operator checks if the left value is less than the right value. For example:
const priceOne = 5;
const priceTwo = 10;
console.log(priceOne < priceTwo);
console.log(priceTwo < priceOne);
- Similar to the operators above, there are also the Less than or equal (
<=
) and Greater than or equal (>=
) operators. For example:
const priceOne = 10;
const priceTwo = 15;
const priceThree = 10;
console.log(priceOne >= priceTwo);
console.log(priceOne >= priceThree);
console.log(priceOne <= priceTwo);
console.log(priceOne <= priceThree)
