How I learn JS from Java ?• It’s more easy If you have write some code
before• I don’t think about variable types for first• I don’t need to create protected, private or
public• I start with define all my function globally• I don’t need to think object oriented for
first• Same with Java, just different syntax (learn
syntax)• Learn back with javascript OOP

JS Nightmare• There is no a good standard
for code convention in JS.• It’s hard to read JS structure.• Too much free role, like
same initialization, unsafe type, free passing.• Some browser support
limitation

My some little error• Have no consistency in naming
file, structure, function, variable• Using == instead ===• Not initialize variable with its
type• Do logic without checking its
undefined or null• Create global anonymous
function in un-relevant file• Create un-reusable function with
almost same function• Have not debug it

Good algorithms are always better than super computers”

Here some of our problem in learning new programming language…
copyright © 2016 irfan maulana for jakartajs
#1 Not enough time
We don’t give time (and sometimes the motivation) to learn.
Good motivation will lead you to spent more time in learning.

#2 Give up
We always give up too soon, without wanna know if we can do it with some little hard work in the beginning.
All great people in your environment is start with hard work and hard learning to be like now.

#3 Forgetting
We forget too quickly about what we learn.
Repetitive learn if you feel weak in remembering anything.

#4 Same Mistake
Do some mistakes in leaning are normal, but when make same repetitive mistake, this is a serious problem.
copyright © 2016 irfan maulana for jakartajs
#5 Lazy to refer
We are too lazy to refer what we learn into primary sources that will make us having more good insight
copyright © 2016 irfan maulana for jakartajs
#6 Don’t Practice
We sometime like to read about technical concept, tutorial or sample of others work.But thinking that we can understand anything without doing, practice, or make some sample is a wrong way.

My Cheat Sheet• Read code regularly with rhythm• Run through it everyday• When found a problem, try to solved
it, loop trial and error• Google it, see stackoverflow, ask your
close friend or mentor • Put in note when you found a diamond• Focus in one problem at the time• Share with other• Never stop learning• Don’t practice to hard
copyright © 2016 irfan maulana for jakartajs
You Must Try in JS• Learn Javascript basic (datatype,
function, loop, flow, etc) • Get online courses• Create your own code and learn to
debug• Build something!• Learning some library or framework• Fix your knowledge for best practice
and high performance code• Power up your skill
