Call parent function which is being overridden by child during constructor chain in JavaScript(ES6) [duplicate]
You seem to be operating under a misconception that there are two objects A and B when you are in the constructor of the derived class B. This is not the case at all. There is one and only one object. Both A and B contribute properties and methods to that one object. The value … Read more
React: this is null in event handler

Arrow Functions and This [duplicate]
Short answer: this points at the nearest bound this – in the code provided this is found in the enclosing scope. Longer answer: Arrow functions do not have this, arguments or other special names bound at all – when the object is being created the name this is found in the enclosing scope, not the … Read more
C# way to add value in a List at index
The .Insert() method on List<T> is exactly for this purpose: someList.Insert(2, someValue); This would modify the someList collection to insert someValue at index 2, pushing other values up one index. More information here.
Javascript: Do I need to put this.var for every variable in an object?
JavaScript has no classes class-based object model. It uses the mightier prototypical inheritance, which can mimic classes, but is not suited well for it. Everything is an object, and objects [can] inherit from other objects. A constructor is just a function that assigns properties to newly created objects. The object (created by a call with … Read more

Calling `this` member function from generic lambda – clang vs gcc
This is a gcc bug. From [expr.prim.lambda]: The lambda-expression’s compound-statement yields the function-body (8.4) of the function call operator, but for purposes of name lookup (3.4), determining the type and value of this (9.3.2) and transforming id-expressions referring to non-static class members into class member access expressions using (*this) (9.3.1), the compound-statement is considered in … Read more
In a templated derived class, why do I need to qualify base class member names with “this->” inside a member function?
C++ answer (general answer) Consider a template class Derived with a template base class: template <typename T> class Base { public: int d; }; template <typename T> class Derived : public Base<T> { void f () { this->d = 0; } }; this has type Derived<T>, a type which depends on T. So this has … Read more
Should I use `this` within a class?
As a general rule, it’s a question of local conventions. Most of the places I’ve seen do not use this-> except when necessary, and that’s the convention I prefer as well, but I’ve heard of people who prefer to use it systematically. There are two cases when it is necessary. The first is if you’ve … Read more
