I'm trying to get a list of all guideScenes in all sections via
let combinedScenes = _.reduce(sections,
(prev, section) => {return {...prev, ...section.guideScenes}},
{}
)
It's only returning the first section list, how do I get all of them in there?
const sections = [{guideScenes: ['hello']}, {guideScenes: ['world']}, {guideScenes: ['hi', 'yo']}]
let combinedScenesObj = _.reduce(sections, (prev, section, index) => {
return {...prev, [index]: [...section.guideScenes]}
}, {})
console.log('object:', combinedScenesObj)<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.5/lodash.core.js"></script>You were close you needed a key to be added to each array because you were trying to add to an object
//dummy data
const sections = [{guideScenes: ['hello']}, {guideScenes: ['world']}, {guideScenes: ['hi', 'yo']}]
if you're wanting to resolve to an object you should give the item a key, for instance, I've used the index in this example
let combinedScenesObj = _.reduce(sections, (prev, section, index) => {
return {...prev, [index]:[...section.guideScenes]};
}, {})
// { 0: ["hello"], 1: ["world"], 2: ["hi", "yo"] }
