Many people might find it hard to believe a language can be built in only 1 week. Having used JavaScript, I find this very easy to believe.

@Jeffrey Rujen Well they've been using it for more than 11.5 days

@jekytck 2 года назад

@Jeffrey Rujen 11.5 days is 276 hours of (assuming) pure coding, which is not "just 11.5 days", especially if we take in consideration that coding can take on average 20% of the whole time if working on the whole project (designing, thinking, evaluating, testing, etc takes about 60-70% if I'm not wrong). Just to have a more clear idea: it's as if they've been working with JS related projects for 1000+ hours as a rough estimation (or more, depending on his position) And even if that's not the case, 11.5 days of something is quiet a lot , in fact it might take 13 weeks of 3hours/day work with 2 days off per week It's not mind-blowing, but it's not just "just" either.

@TheOriginalJohnDoe 2 года назад

I think something that should be worth mentioning is that JavaScript always runs twice, which brings up the topic "hoisting" The first time JavaScript runs it will "hoist" variables and functions to the top of the file and then the second time it will run the code. This is something not a lot of beginners know, but is essential to get a good grasp of how JavaScript works.

@aniruddhasharma5738 2 года назад

Hoisting is why 'var' is avoided.

@Voidstroyer 2 года назад

I suppose that you are talking about the initialization phase and the execution phase. It's not necessarily that javascript runs twice. It just has 2 phases.

@rv264 2 года назад

It’s not running twice I guess . What you are talking about is basically memory allocation in the execution context of the call stack . So even before the code start executing all the variable and functions are allocated memory and then it keeps getting popped out of the call stack

I think it would be incredibly funny to see a video on GML (GameMaker Language). Not only because it serves only one purpose, not only because it is heavily integrated into the GameMaker IDE, but also because it is the most inconsistent mess of a language ever concieved.
