In addition to the prebuilt functions and libraries, developers can also create their own custom functions to use in their programs. This allows developers to create unique and powerful programs that are tailored to their specific needs. Custom functions can also be shared with other developers, allowing them to benefit from the same code.
Objects are created from classes using the keyword ‘new’. This keyword creates a new instance of the class, which can then be used to access the members and methods of the class. Objects can also be used to store data, such as user information or application settings. By using objects, developers can create more efficient and organized code.
It is important to remember that debugging and troubleshooting can be a time-consuming process. It is important to be patient and methodical when trying to identify and fix errors. Additionally, developers should be sure to document their debugging process, as this can help them to identify any patterns or trends in the errors they are encountering.
Frameworks help developers build complex programs faster by providing pre-built functions and components. Popular frameworks include ReactJS, AngularJS, EmberJS, NodeJS, BackboneJS, and MeteorJS. Each framework has its own benefits and drawbacks; developers should carefully select one suitable for their needs.
When selecting a framework, developers should consider the size of the project, the complexity of the application, and the desired features. ReactJS is a great choice for creating user interfaces, while NodeJS is ideal for creating server-side applications. AngularJS is a great choice for creating single-page applications, while EmberJS is a great choice for creating complex web applications. BackboneJS is a great choice for creating lightweight applications, while MeteorJS is a great choice for creating real-time applications.
Common best practices to improve the efficiency of code include always aiming for clean code (comments help), modularizing code into smaller parts (visualizing data in tables helps), variable checking (using isNaN() or isFinite()), eschewing global variables (using local variables whenever possible), writing short but meaningful code snippets, avoiding hard coding where possible, caching expensive operations (using memoization), avoiding script blockers (by following standard browsers conventions) etc.
