{"@context":"https://schema.org","@type":"FAQPage","mainEntity":[{"@type":"Question","name":"What is a method in JavaScript?","acceptedAnswer":{"@type":"Answer","text":"A method is a function that is a property of an object. Methods allow objects to have behavior in addition to data. You define methods by assigning a function to an object property, and call them using dot notation like object.method()."}},{"@type":"Question","name":"What does the this keyword refer to in JavaScript?","acceptedAnswer":{"@type":"Answer","text":"The this keyword refers to the object that is executing the current function. In a method, this refers to the owner object. The value of this depends on how a function is called, not where it is defined."}},{"@type":"Question","name":"Why do arrow functions not have their own this?","acceptedAnswer":{"@type":"Answer","text":"Arrow functions inherit this from their enclosing lexical scope instead of having their own this binding. This makes them unsuitable as object methods when you need to access the object via this, but useful for callbacks where you want to preserve the outer this."}},{"@type":"Question","name":"What is the difference between call, apply, and bind?","acceptedAnswer":{"@type":"Answer","text":"call() invokes a function with a specified this and individual arguments. apply() is similar but takes arguments as an array. bind() returns a new function with this permanently bound to a specified value, without immediately invoking it."}},{"@type":"Question","name":"What is method shorthand syntax in ES6?","acceptedAnswer":{"@type":"Answer","text":"ES6 method shorthand lets you define methods without the function keyword: instead of greet: function() {}, you write greet() {}. This is cleaner and is the preferred way to define object methods in modern JavaScript."}}]}
