Concatenate, but I am not a native English speaker so don’t trust me! xD
I’d advise to install a multi-language dictionary in your browser (from settings/languages in all chromium based browser applications) and set the spell check and correction with a right click:
but I figure once I am more familiar with that syntax it should be as simple as the other stuff.
In this exercise specifically there was a net usage of JQuery which I think was not clever in a JS course, as it is an external library that is dying since several years.
Here on Codeacademy? I don’t remember there was that. But I may remember wrong. I did the Ruby on Rails course, thinking that together with HTML and CSS was enough, so fun (ironic) when I realised that JS would have been a thousand times better choice.
Now I just need to do projects with this and python and Java. I think they’re the last step I need before becoming employable with the skills and finally land my dream job.
I honestly wish you a lot of luck for it! I’m sure that you can do it if you hardwork for it, I’d advise to follow any of the Career Paths course available here on Codeacademy as there are some interesting JS projects that in this course are not present.
Also, I’d advise to check out the API’s for Web Animations (WAAPI) and DOM on MDN website as they’re truly useful in webdev
