**`Infinity`** is a global property of the `global` object. It is a number that exceeds any other number. It is read-only, meaning you cannot modify it. We will try to modify it in one of the examples below. Infinity can be negative or positive, as we know in mathematics.

# 
## Example: Log `Infinity` to the console
In the example below, we will log out `Infinity` to the console.



console.log(Infinity)
console.log(Math.pow(10, 1000)) // Positive infinity

## Positive and negative `Infinity`
`Infinity` can be negative or positive. It is *positive* when the value exceeds `1.797693134862315E+308`, the upper limit of floating point numbers. And it is *negative* when it is `-1.797693134862315E+308`, when a value exceeds the lower limit of floating point numbers.


// create negative and positive infinity values
let negInfinity = -1.797693134862315E+308
let posInfinity = +1.797693134862315E+308

// log to the console
console.log(negInfinity)
console.log(posInfinity)

## What is `Number.POSITIVE_INFINITY`?
**`Number.POSITIVE_INFINITY`** is the initial value or start of `Infinity`. Let's log it to the console and see its value.
