How to convert array of words to make a sentence?

问题

I feel uncomfortable asking, but how do I convert an array of words to make a sentence ?

I keep finding the other way round.

Something like:

var a = ['hello', 'world'];

and obtain :

hello world

This doesn't need jquery. Javascript has a very simple way of doing this with the join function:

a.join(" ");

回答2:

Just join the elements of the array into a string using a space as a separator:

var sentence = a.join(" ");

Do you mean something like?

arr.join(" ");
