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!

Answer 1

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

MDN

Syntax
array.concat(value1, value2, ..., valueN)
