Typescript array foreach with push function (Angular)

Question

I have array:

data
    Array
    (
    [0] => Array
        (
            [name0] => J
            [name1] => L
            [name2] => C
        )

    [1] => Array
        (
            [data0] => 3,1,3
            [data1] => 5,3,2
            [Nu0] => 3,0,0
            [Nu1] => 1,1,1
        )

)

I need push the data to other array

this.datas.push({'name':'A','data':(data[1].data0).'color':'#00000'}); 
this.datas.push({'name':'C','data':(data[1].Nu0).'color':'#00000'}); 
this.datas.push({'name':'B','data':(data[1].data1).'color':'#FFFFF'}); 
this.datas.push({'name':'D','data':(data[1].Nu1).'color':'#FFFFF'}); 
this.namedatas.push(data[0].name0);
this.namedatas.push(data[0].name1);

How to use loop function to do this? Also what to do if I have more data?

1. Share the data array as valid json 2. What is the other array that you are trying to push to? 3. What is the expected output. — Nicholas K

In your case I suggest you to use a map or a filter function:

metadas = datas.map((el) => {
    return el.name;
});

In this case in metadatas array you will have all names contained into datas array.

You can do easily like below in this example we are going to push data from first array items to second array newItems:

Like this is your first array items:

const items = ['item1', 'item2', 'item3']

This is your second array newItems:

const newItems = []

Here is your solution :

items.forEach(function(item){
  newItems.push(item)
})
