Description
It is common for people who are new to JavaScript-or even those already familiar with it-to struggle with correctly using the this keyword and determining its actual value. Despite being used in almost every JavaScript application, its behavior can often seem unpredictable.For example, a general rule states that "the value of this is the object that calls the function." However, this rule does not always hold true-such as when using arrow functions, where this behaves differently. Or what happens when a function is called not by an object, but by a primitive value?Anyone building JavaScript solutions will inevitably use this, making it crucial to understand how it works in different contexts.This course aims to help developers use the this keyword with confidence-without guessing or second-guessing its behavior. It provides detailed knowledge on its usage, starting with core concepts like the global object and gradually diving into more advanced topics, such as this in getters and setters.list of course content:-Introduction-The global object-This keyword in the function context-This substitution process-Explicitly setting the value of this-This keyword in callbacks and arrow functions-This keyword with setter and getter accessor properties-This keyword in event handlers-This keyword in constructors-This keyword within methods
