如何将 2 个 arrays 合并到 Javascript 中的 1 个数组中？

Question

I would like to merge my array into one while creating different objects inside it. The result I want to achieve is:

[{latitude: 19.04890787659077,longitude: 47.49627131324106}, {latitude: 19.07438856746581, longitude: 47.49834420053164}, {etc..}]

My current arrays look like this:

0: 19.04890787659077
1: 18.93150306374864
2: 18.570734077493597
3: 17.948338720442376
4: 18.594379058124062

0: 47.49627131324106
1: 47.44522085405608
2: 47.482922755413774
3: 47.31701880320728
4: 46.052752331223935

The data will be dynamic so I can't solve it by [{latitude: Arr[0], longitude: Arr[5]}, {etc..}]

Answer 1

 const arr1 = [ 19.04890787659077, 18.93150306374864, 18.570734077493597, 17.948338720442376, 18.594379058124062 ]; const arr2 = [ 47.49627131324106, 47.44522085405608, 47.482922755413774, 47.31701880320728, 46.052752331223935 ]; const result = arr1.map((v, i) => ({ latitude: v, longitude: arr2[i] })); console.log(result);

Answer 2

I am not 100% sure what you meant but I think you are looking for one of these:

Array.prototype.push.apply(arr1,arr2);

or

arr1 = arr1.concat(arr2)

These are the old school methods, the new way to do it is

var arr3 = [...arr1, ...arr2]

Answer 3

If you have only one array like this:

const a = [19, 18, 17, 18, 19, 47, 46, 46, 47, 47];

I tried this:

const mid = Math.floor(a.length/2);
const result = a.slice(0, mid).map((el, idx) => ({lat:el, lon:a[idx+mid]}))
