JavaScript tools for development

 Here are the major ways that can help accelerate JavaScript development.

1. Webpack to decrease application size
JavaScript modules have small chunks of code that might increase the size of the application. The larger the size, the more time will it take to load which will impact the user experience. Hence, Webpack can be used, which not only decreases the size of the application but also helps in understanding the code written by the developer.

2. Gatsby by increase performance
A better user experience and customer-oriented businesses are the requirements of the present time. A business needs to ensure that they can offer them to the users that are making the web performance a bit critical. Gatsby can be a great addition to JavaScript development as it improves web performance with the static site generator.

3. TypeScript to Identity errors
JavaScript is a dynamic programming language that can complicate the whole development process. The freedom to use arrays and objects is a plus when it comes to dynamic writing that also includes errors. The errors can be handled easily with the help of TypeScript static typing that allows users to define variables.

4. Semantic-UI to shorten the learning curve
The framework, Semantic-UI can be used to shorten the learning curve using the broad palette of theme, font files, and JavaScript. It offers excellent customisation properties to work on the design elements including responsive solutions for the mobile and web with the UI components.

However, what makes it even more popular is its plethora of libraries that make it easy for developers to work on any project.

Here are the top libraries that a developer must know when it comes to C++.

1. Asio C++ Library
It is used for low-level I/O and network programming that provide basic building blocks and a consistent asynchronous model. It also includes the real-time transaction system and interactive websites along with smartphone games and apps.

2. Active Template Library (ATL)
The library is all about C++ classes that support the Common Object Model (COM) and build features such as standard COM enumerator interfaces, dual interfaces, and ActiveX controls. It is used to build single-threaded objects, free-threaded model objects, apartment-model objects, etc.

3. Eigen
This library includes vectors, matrices, related algorithms, and numerical solvers that offer support to all matrix sizes. It can support all types of standard numeric types that can even include the Eigen features that intelligently remove temporaries.

4. FloatX
Float eXtended or FloatX is the library that is used for the floating-point and low-precision type emulation. Fortran and Python programming language also use this library since it is based on the FlexFloat library.
