String split returns an array with two elements instead of one

Question

I don\'t understand this behaviour:

var string = \'a,b,c,d,e:10.\';
var array = string.split (\'.\');

I expect this:

consol         


        

Answer 1

Because your string is composed of 2 part :

1 : a,b,c,d,e:10

2 : empty

If you try without the dot at the end :

var string = 'a,b,c:10';
var array = string.split ('.');

output is :

["a,b,c:10"]
