Keybase proof

I hereby claim:

  • I am joelnet on github.
  • I am joelnet (https://keybase.io/joelnet) on keybase.
  • I have a public key ASBhE_5H8aJ_C-JIpSwxrk42nUN2c1I_f0Fe6jmlWphKhgo

To claim this, I am signing this object:

const pipe = require('ramda/src/pipe')
const curry = require('ramda/src/curry')
const clampA = (min, max, value) => {
let newValue = Number(value)
newValue = Math.min(max, newValue)
newValue = Math.max(min, newValue)
return newValue
}
