Javascript Array inside an array not working

Question

I am new to javascript. I tried to achieve this output in array but I really cannot do it.

Output should be:

["test", "test1"],
["test2", "test3"]

From this:

The data from items:

items = [
 {
 data1: "test",
 data2: "test1"
 },
 {
 data1: "test2",
 data2: "test3"
 },
]

I tried to push to a new array in here but not working. Is there any workaround here?

 for (var i = 0; i < items.length; i++) {
 items[i]
 }

• Felix Kling: Your loop doesn't do anything. Can you post what you have actualy tried?

Answer 1

Use Array#map method

var items = [{
 data1: "test",
 data2: "test1"
}, {
 data1: "test2",
 data2: "test3"
}, ];
console.log(
 items.map(function(obj) {
 return [obj.data1, obj.data2]
 })
);

Answer 2

A solution using Array.prototype.reduce and listing out all the values from items into an array and not just data1 and data2:

var items=[{data1:"test",data2:"test1"},{data1:"test2",data2:"test3"}];
var result = items.reduce(function(prev,curr){
 prev.push(Object.keys(curr).map(e=>curr[e]));
 return prev;
},[]);
console.log(result);

Here is another solution for you :

jsfiddle

var items= [
 {
 data1: "test",
 data2: "test1"
 },
 {
 data1: "test2",
 data2: "test3"
 },
];
for(i in items){
 array=[];
 for(j in items[i]){
 array.push(items[i][j])
 }
 console.log(array);
}
