Variables: These are utilized as containers for storing data values. They are declared using the
Operators: Arithmetic (
%) and comparison operators (
Functions: These are code blocks designed to execute a specific task. They come into action upon invocation.
Objects: Objects are property collections, with each property being a name-value pair.
Arrays: Arrays facilitate the storage of multiple values in a single variable. They follow zero-based indexing, meaning the initial element is at index 0.
Control Structures: They include
switchstatements, and loops (
do...while) to steer the program’s flow.
Libraries and frameworks such as jQuery, React, Angular, and Vue.js expedite development and enhance code efficiency.
Maintaining best practices can augment your code’s readability, maintainability, and performance. These encompass consistent indentation, code commenting, top-of-scope variable declaration, strict mode usage (
"use strict";), and apt error handling.
