Object.keys
guarantee an order?
converge
-> modArgs
and useWith
-> modPerArg
createModArgs
resolver
arg, index, arguments
(like value, index, array)
useWith
the resolver would be identity
and for converge
it would be function(value, index, args) { return args }
baseModArgs(func, transforms, resolver)
['FY', 'Q3', 'Q2'] => {'FY': [ some filtered stuff here], 'Q3': [ 'some other stuff' ], 'Q2': [ ]}
Use case is when getting some stuff from SQL and transforming into more json like structure
converge
as a name. I do think useWith
would have to be renamed as it can mean anything. How about converge
("To come together from different directions") and disperse
("To strew or distribute widely")? The two words are related because they're kind of opposite, but they also both say something about what happens to the arguments. Besides, I think the subtle differences between the two are too great to name them after the same thing. I'm specifically talking about how the arity for the returned functions is chosen. For converge
it will be the biggest arity of all given transformers, and for useWith
it will be equal to the amount of given transformers.
// input
var input = {
apple: 3,
cucumber: 1
};
// desired output
[{
name: 'apple',
quantity: 3
}, {
name: 'cucumber',
quantity: 1
}];
function transformData(content) {
return reduce(function(output, key) {
output.push({
name: key,
quantity: content[key]
});
return output;
}, [], Object.keys(content));
}
var transformData = R.pipe(R.toPairs, R.map(R.zipObj(["name", "quantity"])))
