Discussion on: Component Lifecycle Methods Explained

Thanks for the nice article, good job! This is a good abstraction of the concepts across tools.

I've often wondered if we have TOO many life cycles. For example, Vue has a before and after for various lifecycle events. Imagine a component using all of them? Hmmm.

What about too few life cycles? Angular we have no pre-component, but we do have the constructor of the component, which could be used for any checks prior to any elements even existing.

Good things to think about. Thanks for raising this.

Thanks John! I found myself thinking similarly as I put this together. React also has a number of methods for both before and after a lifecycle event, but the recent addition of hooks upends that a bit.

My assumption is that some of the poor usages come from people who don't understand the underlying concept. It's not an easy thing to wrap your head around at first (at least with the people I've seen in the learning stage).

Perhaps the availability of methods is not as much of a problem compared to lack of best practices and comprehension.

Good points.

I've also wondered about how people really feel about React hooks. I mean, it is an amazing feature! But does it also cause confusion in the every day developer? Perhaps. Perhaps not.

I suspect it's person-specific? For some, the coupling of state and component lifecycle feels natural. For others, they separate the two in their mind.

I think the one challenge of hooks is that they're purposefully more adaptable. They aren't as explicit with where/how they can be used. It's the "enough rope to hang yourself" problem. And in a lot of cases people don't recognize they're missing some of the background effects of those methods.

you could be right.

often I see post on how to use react hooks, but I bet the posts that show side by side what you would do with life cycle vs a hook, would resonate more. Im sure they exist, I just havent seen those.
