## Math.min and Math.max

You’ve probably heard of and used the `Math.min`

and `Math.max`

functions in JavaScript before, they’re pretty self explanatory.

### Something useful

One trick that I found particularly handy, is when using both `Math.min`

and `Math.max`

together to constrain a number between two bounds.

### Something to take-away

We can use ‘currying’ to create a dynamic constraining function that will constrain numbers to the specified bounds.
