JavaScript does not have a separate data type for integers. Instead, integers are represented using the `number`

data type, which is used to represent both integers and floating-point numbers.

Here are some examples of integers in JavaScript:

```
let num1 = 100;
let num2 = -42;
let num3 = 0;
```

**JavaScript integer example**

Simple example codes perform mathematical operations with integers in JavaScript, such as addition, subtraction, multiplication, and division.

```
<!DOCTYPE html>
<html>
<body>
<script>
let num1 = 10;
let num2 = 5;
let sum = num1 + num2; // sum is 15
let difference = num1 - num2; // difference is 5
let product = num1 * num2; // product is 50
let quotient = num1 / num2; // quotient is 2
console.log("Sum: " + sum);
console.log("Difference: " + difference);
console.log("Product: " + product);
console.log("Quotient: " + quotient);
</script>
</body>
</html>
```

**Output:**

You can `parseInt()`

and `parseFloat()`

to convert strings to integers and floats, respectively.

```
let numString = "42";
let num = parseInt(numString); // num is 42
```

You can also use `Math`

methods to perform more advanced operations.

```
let num = 2;
let power = Math.pow(num, 3); // power is 8
let floatNum = 3.14;
let roundedNum = Math.floor(floatNum); // roundedNum is 3
```

**Is there an integer type in JavaScript?**

**Answer: **In JavaScript, there is no separate integer data type. The `number`

data type is used to represent both integers and floating-point numbers in JavaScript.

This means that when you declare a variable in JavaScript with a whole number value, it is still stored as a `number`

data type, rather than an `integer`

data type.

For example, if you declare a variable with a value of `5`

, it is stored as a `number`

data type, as shown below:

```
let num = 5;
console.log(typeof num); // outputs "number"
```
