The optimal location to declare a constructor in Typescript

When it comes to adding properties in an Angular component, the placement of these properties in relation to the constructor function can be a topic of discussion. Is it best to declare them before or after the constructor? Which method is better - Method 1 or Method 2? And most importantly, why?

Method 1

class Test{ 
     private variableA;
     constructor(){}
}

Method 2:

class Test{ 
     constructor(){}
     private variableA;
}

Answer №1

It is generally recommended to declare variables before the constructor in your code structure. Following the constructor, functions are typically defined. However, this practice can vary based on personal preference and will not affect the functionality of your program.
