I have arrays of arrays which contains something like this:
var values = [[1, 2, 3], [3, 2, 1]]
I've tried .map() and Object.assign but I dont know how to implement it. I want this as an output:
values = [
{'up': 1, 'middle': 2, 'down': 3},
{'up': 3, 'middle': 2, 'down': 1}
]
What should I use? This is what Im came up so far:
const object1 = [[1,2,3],[3,2,1]],
object = []
object1.forEach(function(array) {
object.map(value => ({'up': array[0], 'mid': array[1], 'down': array[2]}))
});
console.log(object)
Not very different from what others already did, but a little more elegant:
let arr = [[1, 2, 3], [3, 2, 1]]; let result = arr.map(([up, middle, down]) => ({up, middle, down})); console.log(result);
you can simply use Array.map()
, there is no need of forEach()
let arr =[[1, 2, 3], [3, 2, 1]]; let result = arr.map((e)=>({"up" : e[0], "mid" : e[1], "down" : e[2]})); console.log(result);
