Alternative to parseInt() - input.valueAsNumber

The problem with HTML inputs is even number type inputs (<input type="number">) return strings when called. Due to JavaScripts untyped syntax, weird things can happen with strings unless you add the safety net of using parseInt() or parseFloat().

I recently found a cool little alternative, input.valueAsNumber! Awesomely, valueAsNumber will return a primitive number regardless of whether the input is 3 or 3.14 (integer or float) which can save you an extra step.

Here is some basic syntax:
console.log(input.valueAsNumber)
// 3.14, not "3.14" ๐Ÿ˜‰

There is one slight caveat - if the input is empty, valueAsNumber will return NaN, so just beware of that.
