Check if props is in nested object

index.js

//It's not the best implementation because will iterate over all props. 
// If one props is undefined, so it's uncessary evaluate others props
function hasProps(obj, props){
  return props.split(".").reduce((result, prop)=> result && result[prop], obj)
}

//Example

/*
const obj = {a:{b:{c:{d:1}}}}
obj.a.b.c.d === hasProps(obj, "a.b.c.d")

obj.a.b.c.e.t.h.j // will throw a error because undefined e props don't have props
hasProps(obj, "a.b.c.e.t.h.j") === undefined // without error =)
