mapWithReduce.js

const names = ['pikachu', 'squirtle', 'charmander']

const capitalize = function (name) {
    const capitalizedFirst = name[0].toUpperCase()
    const rest = name.slice(1)
    return [capitalizedFirst].concat(rest).join('')
}

// map function with reduce
const map = (list, mapFunction) => {

    total.push(mapFunction(next))
    return total

console.log(map(names, capitalize)) // ["Pikachu", "Squirtle", "Charmander"]
