What is negative infinity in JS?

Syntax:

Number.NEGATIVE_INFINITY;

It’s common to use extreme values as a starting point for functions finding the maximum in a set of data. In this case, because elements don’t have a height less than `0`

, it isn’t necessary, but provides better understanding once you’ve seen this concept before.

Consider the following arbitrary example.

```
var data = [ 1, 5, -10000, 50, 1240 ];
function maxData(data) {
var max = Number.NEGATIVE_INFINITY;
for (var i = 0; i < data.length; ++i)
if (data[ i ] > max)
max = data[ i ];
return max;
}
```

This works great in JavaScript because any value compared to `Math.NEGATIVE_INFINITY`

will be greater.
