Слайд 2What Is JSON-FP
Programs are expressed as a JSON object in a

functional programming style.

Слайд 3Ok. That sounds like something serious, but what does that really

mean?

Слайд 4Introducing JSON-FP
JSON-FP uses a JSON object to describe a computer program.

If

you send a JSON object to JSON-FP to run, you could get a very different object in return.

Слайд 5Let’s Start With Something Simple
var expr = {add: 1} ;
jsonfp.apply(1, expr);

Слайд 6var expr = {add: 1} ;
jsonfp.apply(1, expr);
That’s the same as saying

1 + 1
1 → {add: 1} === (1 + 1)

Now you know a JSON-FP expression is as simple as:

{op: option}

Ex: {add: 1}

Слайд 7JSON-FP allows you to replace ‘option’ with another JSON-FP expression.

That makes

things…
interesting.

Слайд 8Changing
{add: 1}
to
{add: {‘

than 10, add 1 to it.’

Слайд 9Another Example
_.map(list, function(page) {
return _.pick(page, ‘title’);
});
The above code uses

underscore/lodash to remove all but the ‘title’ property from a list of pages.

$Another Example_.map(list, function(page) { return _.pick(page, ‘title’);});The above code uses underscore/lodash to remove all but$

Слайд 10If Done By JSON-FP…
_.map(list, function(page) {
return _.pick(page, ‘title’);
});
vs
{map: {pick:

‘title’}}

$If Done By JSON-FP…_.map(list, function(page) { return _.pick(page, ‘title’);});vs{map: {pick: ‘title’}}$

Слайд 11So you may notice the JSON-FP expression can be very concise

and it can help developers to focus on the problem they want to solve.

Слайд 12But that’s not the whole point…

Слайд 13Properties/features of JSON-FP:

Map/Reduce in the distributed environments.
Functional programming
Homoiconic / metaprogramming

Слайд 14Map/reduce, functional programming and homoiconic…

Those are too heavy stuff for

this introduction. We’ll cover them in the coming slides.

But we can talk a little about map/reduce…

Слайд 15If your application has to query data repositories in a heterogeneous

environment, hadoop/spark is NOT a good fit.

Try JSON-FP, life will be much easier.

Слайд 16Any real world applications?

Слайд 17Well, JSON-FP is less than a month old. Interesting applications are

coming…

For now, you can check out newsql (https://github.com/benlue/newsql) which uses JSON-FP to query objects.

Our next generation API services uses JSON-FP, too.

Слайд 18That’s it for now.
