Other languages like Java and C++ have a float, double, integer, etc., to store different numerical values, but JavaScript only has one type to store all numerical values.

In this shot, we will discuss the **`MAX_VALUE`** property of JavaScript `Number`, which returns the highest numerical value possible.

#   
## Syntax

`Number.MAX_VALUE` returns a value of 1.7976931348623157e+308, which is the highest numerical value in JavaScript. You can create a variable and store it for use.

#    
## Code

Below is the code to print the value returned by `Numer.MAX_VALUE`.

var num = Number.MAX_VALUE;
console.log(num);

The value that is greater than `Number.MAX_VALUE` is infinite; let's check if this is true or not.

var num = Number.MAX_VALUE
console.log(num)
var i = 1/0;
console.log(i)
console.log(i<num)

#   
## Explanation
* Line 2 gives a numerical value, which we get from `Number.MAX_VALUE`. 
* Line 3 generates an infinite value. We can also use the `POSITIVE_INFINITE` property to get infinity.
* The last line of output is false because we are comparing `num` (highest numerical value) to `i`(infinite).

`Number.MAX_value` is very useful while coding, and you will mostly see it in data structures and algorithms. 

## Example
The example below demonstrates how to use `Number.MAX_value` to find the smallest value in an array. 

var num = Number.MAX_VALUE;

let array = [23,52,12,31,432,121,442]

for(var i of array){
  if(i < num){
    num = i;
  }
}

console.log(num)

#    
## Explanation
In the example above, we are finding the smallest element of the array. We use `Number.MAX_VALUE` to initialize a variable that will be compared to the first or any element of the list that will always be smaller than `MAX_VALUE`. The only case where the value will be greater than `MAX_VALUE` is when the value is infinite.

* In line 1, we store the value returned by `Number.MAX_VALUE` in a variable named `num`.

* In line 3, we declare an array of size 7 with random values. 

* In line 5, we iterate through the `array`. 

* In line 6, we have an `if` condition to check if the value is smaller or not. If it is smaller, we replace the value with the current value in the `num` variable.

* In line 7, if the condition is true, then we store the value of the array in `num`.

* In line 11, after the completion of the `for` loop we get the smallest number from the array in the `num` variable.


What is JavaScript Number.MAX_VALUE?

JavaScript uses Number.MAX_VALUE to represent the highest numerical value, equal to 1.7976931348623157e+308. Values above it are considered infinite.
