Javascript is dead!

Long live Javascript!

Text

tell me something that you used to fervently believe to be true but you now think is nonsense

javascript is a good language

people who say isomorphic are smarter than me

reference gary bernhart WAT

OOP is the only good way to handle complexity

so js is a bad language but also a dynamic and sort of OO language

 

what's wrong with that?

 

Hoare's billion dollar mistake

 

well in js everything is nullable

What's the root of all evil?

 

money?

 

premature optimisation?

 

"this"

 

give a code sample of what's wrong with "this"

 

talk about the evil of side effects and pervasive mutability - think about using that Harlem Shake exploit to show evil of side effects

 

generally talk about the problems we face

 

talk specifically about problems with angular 

s1 -> c1 -> {{c1}}

s1 -> c2 -> {{c2}}

So what do we do?

 

Linting?

 

Reviews?

 

More and more tests?

"Testing is good, impossible is better" @rtfeldman #elmconf

 

Use a framework? (NS)

 

Angular? React? Ember? Something even cooler?

 

None of this can fix the language

The elephant in the room

 

Use a better language!

 

Everyone transpiles

 

Use a better language

 

Cool - Typescript yeah?

 

No - because "this"

Clojurescript?

 

Maybe

 

Elm?

 

Even better

 

Benchmarks

 

How?

Evangelise

 

Look deeply at your problems

 

Find a small area and try it

 

Don't stick your neck out too far

Really root cause your issues. Are they caused by the language?

Give the example.of an api call changing shape.

Everyone go and learn elm so I can recruit you.
