想自學入行IT(Day 16 修正 + Day 17)

category theory roots from algebraic topology

Ramda default所有function都係curry
同埋所有function個input響最尾
變咗你寫少好多無謂嘢，clean好多
純粹lodash 多人識咁解

const item = find(propEq(“name”,”Bob”),someList)

const someStr = “a,b,c”
const withoutLastItem = compose(
join(“,”),
init,
split(“,”)
)(someStr)


const removeNil =reject(isNil)
removeNil([“a”, null , “b”])
removeNil({a:null})

(其實lodash都有fp version抄返
https://github.com/lodash/lodash/wiki/FP-Guide
只不過多舊魚又無detail doc )

Ramda 原生build for FP，勁過多過loadash個FP好多

快嘅可以一年推晒其實 加油
