Combining arrays in JS

Question

If you have 2 arrays classical and pop:

classical=[\"Beethoven\",\"Mozart\",\"Tchaikovsky\"];
pop=[\"Beatles\",\"Corrs\",\"Fleetwood Mac\",\"Status Quo\"];
<         


        

Answer 1

+ is first converting both arrays to string, and then adding the strings. For this you need to use concat method.

> classical=["Beethoven","Mozart","Tchaikovsky"];
["Beethoven", "Mozart", "Tchaikovsky"]
> pop=["Beatles","Corrs","Fleetwood Mac","Status Quo"];
["Beatles", "Corrs", "Fleetwood Mac", "Status Quo"]
> all = classical.concat(pop)
["Beethoven", "Mozart", "Tchaikovsky", "Beatles", "Corrs", "Fleetwood Mac", "Status Quo"]

Answer 2

Use the Array class concat() method to combine them on a new variable:

var all = classical.concat(pop);
