There are several built-in objects that provide a wide range of functionalities for common tasks. Here are some of the most commonly used built-in JavaScript objects:
- Object: The base object from which all other objects inherit. It provides basic functionality for creating and manipulating objects.
- Array: Used to store multiple values in a single variable. It provides methods for manipulating arrays, such as adding/removing elements, iterating over elements, and more.
- String: Used to represent and manipulate sequences of characters. It provides methods for working with strings, such as concatenation, substring extraction, searching, and more.
- Number: Represents numeric data and provides methods and properties for working with numbers.
- Boolean: Represents a Boolean value, which can be either true or false.
- Function: Represents a function object. Functions are first-class citizens in JavaScript, meaning they can be assigned to variables, passed as arguments, and returned from other functions.
- Date: Used to work with dates and times. It provides methods for creating, formatting, and manipulating dates.
- Math: Provides mathematical constants and functions for performing mathematical operations, such as trigonometric functions, logarithms, and more.
- RegExp (Regular Expression): Used for matching patterns within strings. Regular expressions provide a powerful way to search, replace, and extract substrings based on patterns.
- Error: Represents an error object, which is thrown when a runtime error occurs. Error objects contain information about the error, such as the error message and stack trace.
- Global: Represents the global object, which provides global properties and functions that are available throughout the JavaScript environment. Examples include console, setTimeout, setInterval, and more.
Note:
Each object provides a set of methods and properties that can be used to accomplish various tasks in JavaScript programming.
