How does the this keyword work in JavaScript?
Article Introduction：In JavaScript, this behavior depends on the way the function is called. ① In regular functions, this is determined based on the calling context, such as when the object method is called, and when the object method is called, it points to the global object or undefined; ② The arrow function does not have this, and it inherits this from the outer scope, and is not suitable as an object method that needs to reference the object itself; ③ Common problems include losing this context in callback functions or event processing, which can be solved by .bind(), wrapping functions, etc.; ④ The ES6 class methods do not bind this by default, and need to be manually bound or use arrow functions to avoid context loss.
