I have two arrays, one is dates and the other is prices. I need to create one JS object containing the intersection of these two.
It needs to look like this:
{ date: "2018-01-01", price: 82 }
or
{ date: date[0], price: price[0]}
... for 250 rows.
I know that I can use Object.assign.apply to combine objects, but then I got an object looking like:
{"2018-01-01": 82 }
without the keys. So how do I format the keys?
Thanks!
You can .map() it and ... spread it to combine like:
let dates = [{date:'20-jan-2017'},{date:'20-dec-2016'}];
let prices = [{price:200}, {price:300}]
let combined = dates.map((date, key) => { return {...date, ...prices[key]}})
console.log(combined);If your arrays are the same length, which I assume they are then you can just iterate over them and add both elements into an object array.
let output = [];
for(let i = 0; i < arrLen; i++){
output.push({
date: arr1[i],
price: arr2[i]
});
}
Assuming that both arrays have the same size you could do
const prices = [...] // an existing array
const dates = [...] // another array with the same length
const newArray = dates.map((date, i) => ({ date, price: prices[i] }))
