What are JavaScript objects and how are they created?
Asked on Aug 02, 2024
Answer
JavaScript objects are collections of key-value pairs, where keys are strings (or Symbols) and values can be any data type. They are used to store and manage data in a structured way.
<!-- BEGIN COPY / PASTE -->
const person = {
name: "Alice",
age: 30,
greet: function() {
console.log("Hello, " + this.name);
}
};
person.greet(); // Outputs: Hello, Alice
<!-- END COPY / PASTE -->Additional Comment:
✅ Answered with JavaScript best practices.- Objects are created using curly braces {}.
- Properties are defined as key-value pairs, separated by commas.
- Methods can be defined as functions within the object.
- Access properties using dot notation (e.g., person.name) or bracket notation (e.g., person["name"]).
