.toString();

If "my_array.toString()" returns the string representation of an array, is it necessary to use it when the elements in the array are all strings?

Hello Emmanuel.

It is only necessary if you want to return a single string with all the strings of the array in 1.

If you need to use them with them property of an array, you should not use it.

Maybe you can have a read here if you like:

It may help out with the example.
