question

Hi,

the code which is in this video is

var my_array=[2,3,4]
console.log(my_array.toString());

my_array.push(5);
console.log(my_array.toString());

the video shows us if we dont put toString into console.log, it shows

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

but I used this code on subline text3 I dont need to use toString. when ı use it and I dont use it they show me different result,like

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

why? can you please tell me ?

toString ill convert it to a string..simply by taking each object and putting a comma (,) between. then console will print this basic string.

Result: 

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

If you don't do toString, yes it will still work, but then console.log method takes the raw array and displays it with brackets and colors.

Result:

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

you can think of these two methods as doing the same thing i.e. displaying the contents, but with different string formats.
