javascript array combine variable values

Question

I am having trouble finding the correct wording to find the answer. I am trying to combine elements in an array.

 array[0] = "bob";
 array[1] = "john";
 array[2] = "frank";

 for (i = 0;i<array.length;i++)
 {
 (in php i would use .=)
     var list .= array[i]+"<br>";
 }

What do i replace .= with?

+= in Javascript is the same as .= in php. You just need to be careful with ints and strings — Coin_op

You can just use .join()

array.join('</br>')

In php as well (implode), no loops required.

This is what you're looking for:

 array[0] = "bob";
 array[1] = "john";
 array[2] = "frank";
 array.join('</br>')

And if you do want to keep with your loop then use the += operator:

 var list = '';
 for (var i = 0; i < array.length; i++)
 {
     list += array[i]+"<br/>";
 }
