JavaScript comes with several built-in objects that are integral to its programming environment, including Object, JSON, String, Math, and Date. Object serves as the foundation of the JavaScript object model, providing key methods like toString() for string representation and assign() for object cloning. While assign() creates shallow copies of objects, it does not handle nested properties. JSON stands out as a key built-in object for converting between string JSON data and live JSON objects, being broadly utilized in various applications.
Built-in JavaScript objects like Object, JSON, String, Math, and Date are essential for effective programming in both the browser and Node environments.
The Object in JavaScript not only serves as the root of all prototypes but also offers critical methods such as toString() and assign() for manipulating objects.
The assign() method allows for shallow copying of properties between objects but be mindful that it doesn't clone nested properties.
The JSON object enables conversion between string representations and live JSON objects, making it a common fixture in JavaScript applications.
