concatenation specifics

Curious why we don't concatenate multiple variables and strings on the same line. For example: sentence += ' programmer who wanted to use JavaScript to ' + verb + ' the ' + noun + '.</h2>'; vs the video solution sentence += ' programmer who wanted to use JavaScript to ' + verb; sentence += ' the ' + noun + '.</h2>';

Hi there! I could be wrong, but I feel like this was done for the sake of clarity in the video. It gets pretty messy to show people the code when the instructors scroll way over to the right and then have to go back. In the videos they tend to like to have everything all on the same screen. It seems like this was a style choice made simply for the sake of clarity as your solution would also work.

Hope this helps! :sparkles:

I thought they may have been the case, I couldn't get the code to work when I concatenated multiple objects but It's likely there was just a minor syntax error on my part. Just wanted to make sure it wasn't a best practice scenario (i.e. you should not concatenate x number of objects together because of x reason). Thank you for your quick reply :)

James Joyce On a side note, as you get further along in the JavaScript track you'll find a workshop on a nifty thing called JavaScript template literals which will make this whole concatenation of strings even less messy. It's "syntactic sugar", but makes the code much more readable :smiley: Actually, if you don't mind taking a detour you might check it out at your leisure. It's pretty short and marked as "beginner" level. You can find it here
