Two Fer

[yosevu]

Bonus:

• Default parameter

const twoFer = (name = 'you') => `One for ${name}, one for me.`;

twoFer('Muhammad'); // One for Muhammad, one for me. ✅ 
twoFer(); // One for you, one for me. ✅ 
twoFer(undefined); // One for you, one for me. ✅ 
twoFer(''); // One for , one for me. ❌  
twoFer(null); // One for null, one for me. ❌ 

• Interpolate, bind

/* Version 3 */

// interoplateA :: String -> String
// const interpolateA = name => `One for ${name}, one for me.`;

// interpolateB :: (String, String, String) -> String
// const interpolateB = (before, after, value) => before + value + after;

// interpolateC :: String -> String -> String -> String
const interpolateC = curry((before, after, value) => before + value + after);

// twoFer :: String -> String
const twoFer = name =>
  ifElse(
    isNil,
    always('One for you, one for me.'), // () => 'One for you, one for me'
    // interpolateA
    // interpolateB.bind(null, 'One for ', ', one for me.') // Two functions in one, wrap in another function
    interpolateC('One for ', ', one for me.')
  )(name);

export const twoFer = (name = "you") => One for ${name}, one for me.

This was my first approach and worked like a charm :) I often find myself thinking harder solutions rather than approaching with a simple solution haha, good content I'm enyoing it!
