I am fixing one of the unnecessary calls to the getProp(), however, for performance reason of following functionalities (which may not apply to you), I need call getProp() 2 twice:
ignoreIfNoChange
option- when
Proxy
is not available (in the old browsers or mobile browsers)
That is why this library requires the getProp()
to be a pure function (mentioned in README.md). I am more interested in your use case for lodash/fp/find
, see if I can help to fix the issue.
Hint: getProp()
should simple that only returns a property to be processed, you can you external context (also refer to example 7) to do additional processing outside the getProp()
such as lodash/fp/find
. E.g.,
const iassign = require("immutable-assign")
const findIndex = require("lodash/fp/findIndex")
const nested1 = { a:{ b:{ c:[ {id: 3}, {id: 4}, {id: 5}], d: 1 } } };
const nested2 = iassign(
nested1,
function (n, {index}) { return n.a.b.c[index]; },
function () { return { id: 12}; },
{
index: findIndex(s => s.id == 4, nested1.a.b.c)
}
);

@siassaj May I close the issue? Feel free to reopen the issue, if the above comments did not solve your problem.

@engineforce Thanks for responding, I was caught up with client work. I'll investigate it & take a look.
