    Keybase proof

I hereby claim:

I am bkinsey808 on github.
I am bkinsey808 (https://keybase.io/bkinsey808) on keybase.
I have a public key ASABgt60ToqtxR60jx3lj-SLgk1i-Yk38Il5YftoDV99Bwo

To claim this, I am signing this object:

  
## lambda_calc.ts
/** Identity */
const I = x => x

/** self apply */
const S = s => s(s)

// Church Numerals
const churchZero = f => I
const nextChurch = n => f => x => f(n(f)(x))
const churchToInt = c => c(x => x + 1)(0)

## liberal_let_because_let_is_more_useful_than_const.ts
// consider the following case

let a, b, c
if (condition) {
  a = 1
  b = 2
  c = 3
}

// how would this be refactored into constantly const?

## liberal_let_because_of_reassignment_use_case.ts
// suppose I have the following function.
// in this case message is declared as const following the constantly const convention

const TEMPLATE = `Howdy ${PLACEHOLDER}!`

function welcome(name) {
  const message = TEMPLATE.replace(PLACEHOLDER, name)
  const wordCount = message.split(' ').length
  return {message, wordCount}
}

## liberal_let_because_const_misleads_into_thinking_properties_are_immutable.ts
// suppose I have the following:

const x = { a: 1 }
x.a = 2

// if I want to make x.a itself sort of like a const, i have to do it like this:

const x = {}
Object.defineProperty(x, 'a', { value: 1 })

// suppose I have the following:
