JavaScript JavaScript Foundations Arrays Methods: Part 1

Array returns with .toString() method

I know that the PUSH adds a string to the end of the existing array, taking the [2, 3, 4] and making it [2, 3, 4, 5]. I also understand the reason for using the "my_arrray.toString()" method with the PUSH demonstration to keep the console.log from goofing up. BUT, I am curious about the appearance of the results.

With the .toString() method added, the array appears WITHOUT square brackets...

 2, 3, 4
 2, 3, 4, 5

But without the .toString() method added, they appear with square brackets...

 [2, 3, 4, 5]
 [2, 3, 4, 5]

Does this effect anything? Is this just a representational goof in the console.log? I didn't find any specific info about it on the w3schools.com page about Array .toString() method (http://www.w3schools.com/jsref/jsref_tostring_array.asp)

Yes, toString() method basically convert your Array into a String.

typeof([3,2,4].toString())
==> "string"
