How To: JavaScript - Combine Arrays

The most common way to combine JavaScript arrays is to use the concat() method. The result of the concat() method is a new array with the values of the "source" arrays.


var result = array1.concat(array2, array3, ..., arrayX);


var firstArray = ["value1", "value2", "value3"];
var secondArray = ["value4", "value5"];
var result = firstArray.concat(secondArray);
result === ["value1", "value2", "value3", "value4", "value5"];
