what is the right way to treat Python argparse.Namespace() as a dictionary?
...import argparse
>>> args = argparse.Namespace()
>>> args.foo = 1
>>> args.bar = [1,2,3]
>>> d = vars(args)
>>> d
{'foo': 1, 'bar': [1, 2, 3]}
You can modify the dictionary directly if you wish:
>>> d['baz'] = 'store me'
>>> args.baz

Good or bad practice? Initializing objects in getter
... value is returned. In your implementation this is not the case for null:
foo.Bar = null;
Assert.Null(foo.Bar); // This will fail
It introduces quite some threading issues: Two callers of foo.Bar on different threads can potentially get two different instances of Bar and one of them will be withou...
Modify Address Bar URL in AJAX App to Match Current State
...f a client side function executed this code:
// AJAX code to display the "foo" state goes here.
location.hash = 'foo';
Then, the URL displayed in the browser would be updated to:

How to check for the type of a template parameter?

Usually, that's a totally unworkable design, though, and you really want to specialize:
template <typename T> void foo() { /* g...

Is there a way to provide named parameters in a function call in JavaScript?
...y(null, arguments);
};
};
}());
Which you would use as:
var foo = parameterfy(function(a, b, c) {
console.log('a is ' + a, ' | b is ' + b, ' | c is ' + c);
});
foo(1, 2, 3); // a is 1 | b is 2 | c is 3
foo(1, {b:2, c:3}); // a is 1 | b is 2 | c is 3
foo(1, {c:3}); // a i...
JavaScript single line 'if' statement - best syntax, this alternative? [closed]
...o read or even call it an anti-pattern:
lemons && document.write("foo gave me a bar");
Personally, I'll often use single-line if without brackets, like this:
if (lemons) document.write("foo gave me a bar");
If I need to add more statements in, I'll put the statements on the next line...
Get selected subcommand with argparse
