How to code like a pro in 2022 and avoid If-Else

That's a nice well-written article with good points.

Software Dev Team Lead

Here's a Software Dev Team Lead's way of doing this: No need to even determine the type. Instead the type implements the correct method for itself & there is never a need to even know the base type. Strategy pattern. 😎🤓

Try The Code

Try the code out and see it run at: https://stackblitz.com/edit/typescript-xibe8j?file=index.ts

interface Animal{
  Speak();
}

class Cat implements Animal{
    Speak(){
      alert("meow");
    }
}

class Dog implements Animal{
  Speak(){
    alert("woof");
  }
}

class Lion implements Animal{
  Speak(){
    alert("roar!");
  }
}

let a : Animal = new Dog();
a.Speak(); // woof

let allAnimals = [];
allAnimals.push(new Dog());
allAnimals.push(new Lion());
allAnimals.push(new Cat());
allAnimals.push(new Lion());

allAnimals.forEach( a => a.Speak());

Now I know I am a mid-level! 😅

Thanks Thai Tran! It was an interesting read.

p.s. I think you're doing a great job and people would love to follow your work, if you're using any social media (LinkedIn, Twitter) consider adding them to your Hashnode profile. :)

Starter here.

Realised I am a junior ...lol 😅😅😅

...and a Lead developer would create a data structure.

This is totally on point.

Excellent read, thank you Thai Tran

Time to level up!

I am a senior programmer and I avoid IFs althougheter by using polymorphism

Your "senior" example violates Open Closed Principle

So, IMHO article is nice but incomplete

I was reading this article thinking "Man! I've NEVER encountered ANY of these methods in all my years of writing code! I'm mid-level at best and I need to go back to the drawing board and start from scratch."

THEN I realized you're writing .NET.........not JavaScript/TypeScript. 😩🤣

The post is very informative, I learn a lot from it. Thank you, Thai Tran.

Nice article Thai thanks a lot for introducing those different implementations, but it doesn't stand only for if-else statements, what values a developer is his/her ability to communicate and lead in addition to writing a well designed code etc..

With the examples given, it's safe to say that I'm still a junior developer 😃

I think if & else makes the job more easier and efficient. The other way around is great though, but looks kind of odd to understand

Thanks Thai

Wow, nice tricks for senior dev level 👏

Pretty neat and yes thats true for a senior developer

even if i am senior i will go with switch, "easy is best"

Interesting write up Thai Tran 💪

The solution isn't entirely my style, but I support it. I actually really love polymorphism, which is what attracted me to OOP.
