Transcripts
this week I published a list of the top
five Technologies you should learn to
land a web developer job in 2024 and
react was at the forfront learning a new
technology and keeping Pace with its
Evolution can be challenging Concepts
become outdated and new libraries in the
ecosystem often take over in this video
I will guide you through the react
learning path for
2024 while this is based on my personal
experience having created a react
playlist with over 20 million views I
assure you you're in capable hands I've
split the react learning path into three
sections starting with the fundamentals
let's dime in and start building the
foundation that will turn you into a
react Pro in 2024 we finally say goodbye
to create react app embracing wheat as
the new standard for creating react
projects once your wheat react app is
set up it's time to dive into the core
technical concepts of react react
applications consist of reusable code
known as components you learn about
function components known for their
Simplicity the era of class components
is completely fading making function
components the primary focus when
creating components you might initially
be puzzled by the concept of writing
HTML code within JavaScript that would
be jsx which is the heart of reacts
expressive capability it is how you will
write your UI combining the best of
JavaScript and HTML when working with
ACT writing modular code is essential
you learn to Import and Export
components maintaining a clean and
manageable code base next explore react
fragments for grouping jsx elements
without adding extra Dom nodes it is a
subtle yet powerful feature for
efficient
rendering after structuring your UI
explore styling the components there are
various modern approaches but starting
with inline Styles is a good initial
step you you will then encounter props
short for properties a fundamental way
to pass data between components
mastering props is crucial for building
Dynamic applications however props are
readon a component cannot modify its own
props this leads you to the concept of
state state allows react components to
change their output over time which in
turn reenders the UI to alter state in
function components you'll use the used
State hook hooks are essential for
leveraging react features in your
components and UST state is a prime
example with State you can change
component values and conditionally
render the UI understanding the various
methods for conditional rendering in GSX
is your next step you will also learn to
render lists of items efficiently and
bug free using the key prop we all know
user interactions are vital so you will
learn the react way of handling events
to make your applications responsive and
interactive forms are everywhere and
handling them rightly in react is
crucial learn about controlled and
uncontrolled components and how to
collect and submit user input seamlessly
then explore the concept of composition
over inheritance in component design
this design pattern will shape how you
create reusable and scalable components
in react finally a react component goes
through various faces like mounting
updating and unmounting
understand these using the use effect
hook which is key to managing side
effects in function components by
progressing through these topics you
will gain a solid understanding of react
fundamentals moving on from the
fundamentals you're now ready to tackle
the advanced topics in react this is
where you truly begin to refine your
skills and dive into the more complex
aspects that will set you apart as a
react developer almost every modern web
applic apption needs to interact with
apis so you will learn how to make HTTP
requests such as get post put patch or
delete using react mastering these will
allow you to handle data from any
backend service next you'll tackle react
context to solve the problem of prop
drilling the create context API and use
context hook will help you manage State
elegantly across your entire application
this is crucial for maintaining a clean
data flow without any mess you will then
explore refs using the use ref hug and
the forward ref API which will help you
manipulate the Dom directly when
necessary although react typically
discourages direct Dom manipulation
knowing when and how to use refs is
essential for advanced scenarios diving
deeper into hooks you will expand your
knowledge Beyond use State and use
effect you will work with use reducer
for complex State scenarios the new
added use hook for reading values from
resources like promises or context and
use optimistic for optimistic UI updates
you will also learn to create your own
custom hooks once comfortable with these
you can explore additional optional
hooks use debug value use ID use
imperative handle use insertion effect
use layout effect and finally use sync
external store error handling is next on
your path you will learn to use error
boundaries to handle exceptions
gracefully preventing a single component
error from crashing your entire
application and ensuring a better user
experience with portals you will render
components in a do node that exists
outside the Dom hierarchy of the parent
component this is especially useful for
models tool tips and other UI
overlays you will then dive into three
built-in components that react provides
the profiler component assess and
performance analysis helping you make
decisions to optimize your components
strict mode acts as a spell checker
identifying potential problems in your
code early on and suspense helps with
data fetching and code splitting making
your app interactions smoother and
reducing load times you will then
explore performance optimization
techniques hooks like use memo use
callback use transition and use deferred
value help a lot in this regard you will
also learn about memorization with memo
easy loading components with easy and
managing transitions with start
transition finally you will embrace the
new paradigm of react server components
with the newly introduced cache and two
hooks namely use form State and use form
status you will build server rendered
components that can interact seamlessly
with client side components unlocking
new capabilities and performance
optimization by mastering these Advanced
topics you will be able to build
sophisticated and efficient react
applications this knowledge is what will
make you a highly sought after developer
in the react ecosystem speaking of react
ecosystem let's take a look at other
packages which play well with react and
help you create awesome react app let's
take a look at our third section in the
react ecosystem State Management is your
first stop explore client State
Management with suan or Redux toolkit
and for serice State Management consider
tanack query or for Redux toolkit
query next you will navigate new pun
intended the world of
routing understand how to present
different components as users visit
different URLs react router has been the
standard but keep an ey on tanack router
V1 released just last week as it appears
to be very promising styling your react
apps is next you can get started with
CSS injs Solutions like style components
or emotion both of which are widely used
or you can choose tailin CSS which has
become popular for its utility first
approach for a quick start UI component
libraries like material UI Mantine or
shadan UI offer predesigned components
that can accelerate your development in
react handling complex forms is simpler
with react hook form but also look out
for Tan stack form which promises to be
another strong Contender after it V1
release for testing you will use v test
alongside react testing library for unit
tests and for end to-end testing
consider playrite or Cypress next let's
go over a few miscellaneous topics you
should consider learning first is
typescript typescript not only reduces
bugs by adding types to your react apps
but also enhances the developer
experience with improved
autocompletion another essential tool is
Storybook which helps with component
documentation and testing for
internationalization experiment with the
react I8 next package which simplifies
adding multiple languages to your
application when it comes to
authentication Firebase and superbase
are good choices offering a
comprehensive Suite of tools for secure
user management looking ahead if your
path remains web focused next yes is the
framework to specialize in and if you're
drawn to mobile development react native
particularly with Expo offers a powerful
platform to expand your skills let me
know in the comment section what excites
you about learning in
2024 so this is my react learning path
