Welcome to the twelfth Easy JavaScript Tutorial, Beginner JavaScript Tutorial, part of Easy Programming! This tutorial covers Numbers!
Just like strings (and everything else in JS), numbers are also objects and they contain built in methods and properties that you can apply. You can even convert a number to a string and then apply the string methods to it.
Let's learn JavaScript Number Methods!

MAX_VALUE | Property which returns the largest possible number - Number.MAX_VALUE |
MIN_VALUE | Property which returns the largest possible number - Number.MIN_VALUE |
toString() | Converts number to String - same as String() |
toExponential() | Converts number to exponential notation |
toFixed() | Returns a string with a specified number of decimals |
