I am currently learning JavaScript, and just came across Switch Case vs If Else. The tutor said he thinks If Else is better, as the code is shorter, but it comes down to personal preference.

What is the current opinion of Select Case vs If Then Else within the VBA developer community?

I agree. Case is more extensible than If/Then. So, for simple logic, use If/Then, else use Case.

I agree with @theDBguy and @plog
I responded to a post here where someone had put 6 or 7 nested if , elseif , else statements together and it was unreadable and really difficult (nigh on impossible) to follow the logic.

A select case type statement is so much cleaner and easier to follow and debug.

why are you asking the VBA development community, Jon?

CASE statements and IF,THEN,ELSE statements exist in every language. and the difference between the two, with regard to efficiency, is so marginal, why even care? Is your tutor afraid the world is going to run out of energy? :p If they are, I wouldn't be surprised one bit.

I tended to use Case when I had a larger numbe of examples. To me, it looked clearer and easier to understand when glancing. That is why I was surprised to see this very experienced coding tutor suggest if else.

Here are the JavaScript versions. Maybe they have more syntax in Switch Case vs If Else when compared to the VBA equivalents?

let role = 'guest';
switch (role) {
case 'guest':
console.log('Guest User');
break;
case 'moderator':
console.log('Moderator User');
break;
default:
console.log('Unknown User');
}
//Moss prefers this:
if (role === 'guest') console.log('Guest');
else if (role === 'moderator') console.log('Moderator');
else console.log('Unknown User');

The tutor is this guy: https://codewithmosh.com/

He is an excellent tutor.

I also agree with Plog. I took a couple of Mosh's C# classes; he is a good instructor.

as you can see, Jon, break; is necessary to get out of the block. whereas, with the alternative, none of that is used. thus, you way is probably best. less to look at.

by the way, did you know that break and return are brother and sister? =)

Did you persist wity C#? Or are you building up your various programming languages?

how good can he be if he's working for an org that is doing what they're doing because they're getting rich off of a massive trend, just like Bob Parsons did? and what they big data warehouse people are doing now? :(


and why does his other page have no SSL on it!? it only costs $80 bucks a freakin year!


and considering that he has the word ""awesome"" in his gitHub repos, I'm guessing that he's not welcome in the corporate world because he has a caring soul, and thus he became a teacher. I see that with millions of people literally. you have to be a complete ass to survive in the corporate realm:

My employer suggested it as they way they wanted to move forward. They've since backed off that path. I'll probably try to keep learning, but for me it's harder without a project to apply it to.

I was learning Ruby on Rails. But recent things I've read are questioning whether or not I am on the right path. So, I am considering a pivot to learning JavaScript, Django and Python. I went to Google Trends to do some reasearch.

The relative decline in the use of Ruby on Rails suggested to me that perhaps the best path would be Python + Django. Besides, what I have learned about Ruby on Rails so far (besides my previous programming experience), tells me it is mostly a question of mastering the different syntax. The principles are similar.

I agree with everyone else. Sometimes I forget about Select Case and impulsively go to If, then change it back once it starts to get out of hand.
I also like how you can line things up (indents and all) with select case a little easier than If and then ElseIf lines, very trivial perhaps, but I am obsessive about readability.

No one cares about Ruby john. You won't get any work learning it. Django is heavily used by a lot of people however the elite people do not use it. They use their own stuff proprietary

OMG I just got stuck in a nasty for loop that froze up my PC. Then I had to switch computers to find out how to escape it! I blew threw half an hour wasting time on a solution!

JavaScript:
for (let i = 1; i = 5; ++i) {
  console.log('Hello World', i);
}

Next, my computer froze and rebooted, I think. I was away from my computer and came back, with the browser saying Restore pages? and Finder closed etc. Still not sure how to escape a code loop if stuck in vs code.

Got stuck in another infinte loop again. Drat! Need to get to a solution for this.

Edit: Found you have to close the tab or Force Quit Chrome. I would have thought there would be some keyboard shortcut to escape a loop. I'm sure there is in VBA?

ummmm...I believe it's supposed to be:
Code:
for (i = 0; i < 6; i++) {
     console.log('Hello World', i);
}
ya super-nice person! LOL

G O O F B A L L. quit sensoring my stuff!
