Discussion on: Daily Challenge #34 - WeIrD StRiNg CaSe

[Sung M. Kim]

I've implemented based off of La blatte's answer.

const caser = {
  0: c => c.toUpperCase(),
  1: c => c.toLowerCase()   
}
const mod = i => i % 2
const weirdCase = text => text.split(' ').map(word => 
    [...word].map((c, i) => caser[mod(i)](c)).join('')
).join(' ')

console.log(["String", "Weird string case"].map(weirdCase))

prints,

["StRiNg", "WeIrD StRiNg CaSe"]
