Write better React, compose multiple functional HoCs, Higher-Order Components - Array.prototype.map

hof.js

// Result is [2,3,4]
[1,2,3].map((number)=>number+1)

// Note that you can extract the callback function and pass it to the map function:
function addOne(arg){
    return arg+1
}

[1,2,3].map((number)=>addOne(number))
// or
[1,2,3].map(addOne)
