we commonly assign stuff in if statments like this:
if (variable = someFn()) {
//do something with variable
}
This results in lint and IDE warnings (did you mean ==?).
It is better to be explicit about our intention and wrap the assignement
into parens:
if ((variable = someFn())) {
//do something with variable
}
Doing so suppresses warnings + is easier to understand the intention.
I verified that the closure compiler strips the extra parens, so there
is no byte overhead for this safety practice.
We should use this style going forward...
- Speed improvements (about 4x on flush phase)
- Memory improvements (uses no function closures)
- Break $eval into $apply, $dispatch, $flush
- Introduced $watch and $observe
Breaks angular.equals() use === instead of ==
Breaks angular.scope() does not take parent as first argument
Breaks scope.$watch() takes scope as first argument
Breaks scope.$set(), scope.$get are removed
Breaks scope.$config is removed
Breaks $route.onChange callback has not "this" bounded
the flag must be in all src and test files so that we get the benefit of
running in the strict mode even in jstd
the following script was used to modify all files:
for file in `find src test -name "*.js"`; do
echo -e "'use strict';\n" > temp.txt
cat $file >> temp.txt
mv temp.txt $file
done
they have no significant effect on minified and gziped size. in fact
they make things worse.
file | before | after removal
----------------------------------------
concat | 325415 | 325297
min | 62070 | 62161
min + gzip | 25187 | 25176
The bottom line is that we are getting 0.05% decrease in size after
gzip without all of the hassle of using underscores everywhere.
select (one/multiple) could not chose from a list of objects, since DOM requires string ids.
Solved by adding index formatter, which exposed incorrect handling of formatters in select
widgets.
Support ISO 8601 extended format datetime strings (YYYY-MM-DDTHH:mm:ss.SSSZ) as defined
in EcmaScript 5 throughout angular. This means that the following apis switched from
YYYY-MM-DDTHH:mm:ssZ to YYYY-MM-DDTHH:mm:ss.SSSZ (note the added millis) when representing dates:
- angular.Date.toString
- angular.String.toDate
- JSON serialization and deserialization (used by json filter, $xhr and $resource)
