REACTJS PROS N CONS

Sarthakux — Fri, 26 Jun 2020 14:07:18 +0000

ReactJs is one of the most favoured and popular front end development library based on Javascript programming language for developing innovate user interfaces for single page applications.
One of the best choices of developers,it allows developers to create reusable UI components which help in fast development.
Now let's have a look at the pros and cons of ReactJs.
PROS-

Virtual DOM
Reactjs has a virtual DOM which improves app performance by
allowing a page to immediately receive a response from the
server and display updates. Each time a change is triggered,the
entire virtual DOM is updated hence increasing the efficiency of
ReactJs.
Reuseable Components
ReactJs supports reusable components i.e. once a UI component
is created,it can be used in other parts of code or even in
different projects with little or no changes.
While developing a ReactJS app,it is possible to use open-source
libraries of pre-built components.This helps to cut down the
time required for UI development.
Downward Data Flow
Thee one-way data flow in ReactJs is one more feature
developers consider beneficial. This data flow is also called
top to bottom or parent to child. It means there is only one way
data transmission between the elements in a ReactJs
application. A downward data flow prevents errors and

facilitates debugging.
Huge Community
The ReactJs community supplies tons of valuable libraries that
facilitates the ReactJs development process. ReactJs libraries
provide developers with new possibilities and ways to improve
the quality of their code and apps. Since ReactJs developers
often share the libraries with ready to use components,there is
an opportunity to implement some of them in your own application
and reduce the time required for development.
React Developer Tools
React Developer Tools is an extension for Chrome and Firefox
that provides a set of inspection widgets to facilitate
development. The extensions simplify debugging, allowing
developers to search through a list of all components and view
deeply nested components straight in a browser.

CONS OF REACTJS

Poor Documentation
Documentation of ReactJs and its related libraries is often
lacking. Developers tend to release updates to libraries without
updating the documentation. This makes it hard for others to get
acquainted with new features and integrate libraries.
JSX
Yes, JSX is a barrier as it is complex for new developers to
understand its complexity correctly and work on the projects
like a pro.
In fact,JSX is suitable for ReactJs,in many cases.It enables
developers to mix up HTML and Javascript together while it may
provide bad experience to the fresher.
View Part
As ReactJs is used for developing the dynamic user interface,it
has good reasons behind,but it has some adverse impact as well.
For example, developers need to rely on other technologies as
well.

JAVASCRIPT VS PYTHON

Javascript and Python are arguably the two most popular languages today for programmers.
Let us compare the two respective programming languages.

Javascript is good for building a website or native applications whereas Python is good for data analytics,machine learning or math-intensive operations.
Javascript can be used to run on frontend whereas Python is on server-side or backend.
Python has procedural programming whereas Javascript does not have procedural programming.
Python is a better designed language which makes it easy to maintain whereas Javascript is poor.
Javascript is good for mobile development whereas Pyhton is not good for mobile development.
Javascript is faster to run as commpared to Python.
Javascript runs on both server side as well as on browser, whereas Python is mostly used for server side programming.
Unlike Javascript, Python does not have a way to inherit from instances.
Javascript only has floating point numbers whereas Python has different numeric types like int,float,fixed-point decimal,etc.
Javascript uses curly brackets whereas Python uses indentations.
Both these languages have their respective uses and in the end it all comes down to personal preferences.

1) STOP WASTING TIME-

* Cut down on checking social media.
* Turn off notifications.
* Look for apps that limit your time on certain apps.

2) PLAN THE STRUCTURE OF YOUR PROJECT-

Chunk your work into smaller tasks.
Follow the workflow.
All projects are different, you may need different templates.

3) CODE FASTER-

Try using keyboard shortcuts.
Find tools that speed up your work.
Improve your typing speed.

4) DO NOT DRAIN YOURSELF-

Take small breaks at regular intervals.
Overworking can cause fatigue.
Breaks will clear up your stress to some extent.

5) FOCUS ON YOUR GOALS-

Try minimizing distractions.
Don't overthink and under-think.
Create a peaceful and productive work environment.

6) MAKE A DEADLINE-

It leads to more work being done in a limited time frame.
It helps in eliminating procrastination.

7) REGULAR PHYSICAL EXERCISE-

Regular physical exercise keeps body and mind healthy and the individual in harmony with nature.
