I still have to Google...

Javascript foreach loop syntax.

for(var x as y) {

No...

foreach(var x in y) {

Nope...

... checks...

x.forEach(function(y) {

That’s the one I’m after!

Hi, I’m Jake, a lead developer. I’ve been programming for 15 years, 10 of those professionally.

This is something I continually try to get over to students/new developers. Even after all these years there are things I can’t remember and have to look up.

So, what do you have to google?

I will also never remember the right flags for tar...

As I look through my browser history, I googled several times for the text equivalent of some Markdown emojis. 😄

• when I need to use more than one parameter for the various JS array methods
• findIndex vs. indexOf
• slice vs. splice
• date formatting strings for moment.js
• the CSS for truncating text to ellipsis

Yep, only been doing this dev thing for 4 years now...

[Jacob Baker]

Oh jeez, date format strings is another one I don’t think I’ll ever remember. Especially because I spent a lot of time using PHP way back when so I automatically write H:i:s rather than HH:mm:ss when trying to display the time...

Just today, I had to Google C# syntax for Case/switch 😂 and I've been at this for 6+ years 😁

Pretty much anything I don't use on at least a weekly basis. I usually check manpages first though when that's an option, because I can often find what I'm looking for that way far faster than I can with Google.

FWIW, of the languages I've used, I found myself doing it more with JS for core language functionality (that is, stuff that's part of the ECMA standard in this case, as opposed to web API's) than any other language I've tried, even stuff as 'out there' as Erlang or Perl in terms of syntax. And I know quite a few other developers who would almost certainly say the same, which really says something about JS IMO.

[Jacob Baker]

Yeah I would second that; JS tops it out of all the languages I use.

[Sree Chandan R]

I google lot of syntax things especially as I keep jumping between languages.

If I google something more than 5 times I started to keep notes on it. I started this pretty recently. Now I'm slowly realizing as the number of notes increases looking up a note might take longer than actually googling it XD

Switch statements in JS. Every. Single. Time. Also reduce. Both of these just have a syntax that is fairly unique.

[Jacob Baker]

Then switch to Python, type out what should be a switch statement, run it, fails... Google it... Slowly remember Python doesn't actually have a built-in switch statement

[James King]

Take my upvote for having the same problem as me. Nothing in JS is like it (that I've come across yet).

[Chandu J S]

I have to google for bootstrap carousel code every time I need it. 😐

[Anton Melnyk]

Well maybe not forEach loop 😀, but complex things like regex, time formatting, functions like reduce... Sometimes indeed you can google it even if you wrote them one hundred time already!

[Zane Milakovic]

DuckDuckGo....

For me it is switch syntax. I know it, but I always question myself, idk why. And I have been doing this for 18 years. It’s like a instinct now.
