Question

Safari 6:

> ['a=23', 'b=234', 'c=23'].join('&');
"a=23&b=234&c=23"

then with a variable I need to do this with. it’s

jsss
  [
  Array[8]
    0: "s=1"
    1: "l=NTA4NTQzNnw0NzczOTg"
    2: "r=-1"
    3: "t=a"
    4: "m=0"
    5: "si=5156695"
    6: "u=5085436"
    7: "sn=mip"
    length: 8
    __proto__: Array[0]
   ]

> jsss.join('&');
"s=1,l=NTA4NTQzNnw0NzczOTg,r=-1,t=a,m=0,si=5156695,u=5085436,sn=mip"

Why does it seem to ignore the separator?

Answer 1

It looks like you have an array with a nested array, so you’re only calling join on the top array which only has one element (the child array) and therefore just echoes that array with default behavior and nothing to delimit.
