title: Most efficient way to concatenate strings in JavaScript?
body: <p>In JavaScript, I have a loop that has many iterations, and in each iteration, I am creating a huge string with many <code>+=</code> operators. Is there a more efficient way to create a string? I was thinking about creating a dynamic array where I keep adding strings to it and then do a join. Can anyone explain and give an example of the fastest way to do this?</p>
