Bootstrap and custom CSS Classes

I would like to suggest that when writing html classes, we should start with bootstrap class names and then write our own.

❌ Wrong

<div class="d-flex bf-card flex-column bf-component mx-5 pl-5">

👌 Good

<div class="d-flex flex-column mx-5 pl-5 bf-card bf-component">

JS Widgets events

I would also like to suggest to keep events (on a JS widget) as much separated by selector as possible. This is not merging selectors on one event, prefer creating a new line for that element. Or even better, to find a class that can synthesize on one event

❌ Wrong

...
events: {
  'focusin #form-checkout__cardholderName, focusin #form-checkout__cardExpirationMonth, focusin #form-checkout__cardExpirationYear ': 'handleCleanError',
}

👌 Good

...
events: {
   'focusin #form-checkout__cardholderName': 'handleCleanError',
   'focusin #form-checkout__cardExpirationMonth': 'handleCleanError',
   'focusin #form-checkout__cardExpirationYear': 'handleCleanError',
   'focusin #form-checkout__securityCode': 'handleCleanError',
   'focusin #form-checkout__identificationNumber': 'handleCleanError',
}

⭐ Better: creating a class that can propagate the event to all the elements with it

...
events: {
   'focusin .form-checkout-validate': 'handleCleanError',
}

Questions on Access a Dictionary Element part.

I can see is for a dictionary where we are not secure about it has a specify key, Is OK if we use?

value = d['foo']

when We know exactly the structure of one directory

Thanks for notice the broken link and your suggestion in git section @Fabfm4

About your question with dictionaries, I just see something that could be a problem, If the dict changes in structure then de use of value = d['foo'] will return an Exception and using the get() function we always have a value

Nice!, I get it, Thanks @leonardoAlonso :)
