fill an array with objects from other arrays

Question

I have three arrays:

var arrayOne=[{obj1}, {obj2}, {ob3}];
var arrayTwo=[{obj4}, {obj5}, {obj6}];
var arrayThree=[{obj7}, {obj8}, {obj9}];

And I need to Know how to fill a new array with values from those arrays, like this:

var arrayFINAL=[{obj1}, {obj2}, {ob3}, {obj7}, {obj8}, {obj9}, {obj4}, {obj5}, {obj6}];

I thought it was something like this:

var arrayFINAL = new Array(arrayOne, arrayTwo, arrayThree);

But it seems to create an array an array's of arrays not an objects array. Anyone knows how to do this? thnks!

... why are you switching arrayTwo and arrayThree in your example? — ninjagecko

var combinedArray = arrayOne.concat(arrayTwo, arrayThree);

MDN

You're looking for Array concatenation

arrayFinal = arrayOne.concat(arrayTwo, arrayThree);

See here for documentation

Your code...

var arrayFINAL = new Array(arrayOne, arrayTwo, arrayThree);

Will make an array arrayFINAL with three members, each of which is another array, like a multidimensional array.

If you want to create a new array with all three, use the concat() operator...

var arrayFinal = arrayOne.concat(arrayTwo, arrayThree);

jsFiddle.

If you want to push them all onto the original array, use...

arrayOne.push.apply(arrayOne, arrayTwo.concat(arrayThree));

jsFiddle.

You may be interested in array_merge from PHJS - the behaviour you're looking for is identical to what PHP's array_merge does, and the PHPJS version does the same in JavaScript.
