Iteration Push Alternative Javascript

Question

Obviously, this is not allowed in javascript:

for (var i=0; i<data.length; i++){
    array[i].push(data[i].name);
}

Does anyone know of a workaround that does the same thing?

Can you provide `data` variable and be more explicit on what you want to do? — Yosvel Quintero, May 20 '16 at 22:16

You can do

for (var i=0; i<data.length; i++){
    array[i] = [];
    array[i].push(data[i].name);
}

doesn't this just makes lots of little arrays, each consisting of 1 name? I am NOT saying its wrong, but trying to understand the outcome. Thx – gavgrif May 20 '16 at 22:17
@gavgrif That is correct. But that is what the Alexey wants looking at his code. – Maantje May 20 '16 at 22:18
@gavgrif Yep. This works perfectly. – Alexey Ayzin May 20 '16 at 22:19
I guess I am just trying to understand the desired outcome and why all the names can't be pushed into one array and accessed from that. – gavgrif May 20 '16 at 22:20
@gavgrif the reason is because the way my data coming out needs to have the same format as the data coming in. – Alexey Ayzin May 23 '16 at 14:05

but Alexey Ayzin, shurely this is the better alternative - create a single array, push the desired values into it and then access it via normal means::

arrayTest = [];
for (var i=0; i<data.length; i++){
      arrayTest.push(data[i].name);
}

This will give arrayTest all names, and can be accessed as:

var testName=arrayTest[3];

Doing it the other way will give you lots of unnamed arrays - how are they to be used?
