syntax - JavaScript property access: dot notation vs. brackets? -

other obvious fact first form use variable , not string literal, there reason use 1 on other, , if under cases? in code: // given: var foo = {'bar': 'baz'}; // var x = foo['bar']; // vs. var x = foo.bar; context: i've written code generator produces these expressions , i'm wondering preferable. (sourced here .) square bracket notation allows use of characters can't used dot notation: var foo = myform.foo[]; // incorrect syntax var foo = myform["foo[]"]; // correct syntax secondly, square bracket notation useful when dealing property names vary in predictable way: for (var = 0; < 10; i++) { somefunction(myform["mycontrolnumber" + i]); } roundup: dot notation faster write , clearer read. square bracket notation allows access properties containing special characters , selection of properties using variables another example of characters can't used dot notation prope

c# - Equivalent to WPF DependencyProperties in Prism ViewModels -

-
i understand standard way in wpf expose custom property in xaml define dependencyproperty in view’s code-behind. however, works dependencyobject s, such usercontrol . yet, in clean prism fashion, code-behind (i.e., class deriving usercontrol ) empty, , deal logic in view model, derives bindablebase , not child class of dependencyobject . consider following xaml fragment: <mynamespace:mycustomview myproperty={binding} /> the core of mycustomviewmodel is private string myproperty; public string myproperty { { return myproperty; } set { setproperty(ref myproperty, value); } i’m still relatively new prism. do expose myproperty , defined in mycustomviewmodel can set in xaml tag similar above? update following @mm8’s answer , our discussion in corresponding comments, developed minimal (non-)working example of have in mind. summary first: data model list of objects. shell must display each of these objects means of custom user control object type. a)

sql server - SQL : query large table -

-
i want query large data set in sql - right approach? declare @datetime datetime select * sales salesdate <= @datetme or: select * sales salesdate < (select getdate()) or: select * sales salesdate < getdate() or using now() all 3 have same execution plan other 0% assign stage variable in query no. 1. turn out practice in long run initialize variable datetime , use comparison. when have long comparisons make way, user habit of formatting datetime in variable , comparing column against variables. otherwise, becomes habit of formatting sql column , comapring date. formats datetime field in every data row comparison value , makes datetime comparisons slow. for particular query, readability , ease of use, can select query no. 3 [select * sales salesdate < getdate()]. wiki

arrays - JavaScript object stores previous values even in new object -

-
javascript behaves weirdly in case of objects. although i'm not sure if correct behaviour. inside new object(), set properties in object. next time when again new object(), instead of default values values set in previous instance. argh. below example explains problem clearly function testo() {} testo.prototype = { obj: { what: { value: 5 } }, done: function () { console.log(this.obj.what.value); this.obj.what = {value: 10}; } }; var x = new testo(); x.done(); var y = new testo(); y.done(); the output of above code is:- 5 10 i expecting be:- 5 5 why? because i'm creating new class() , in previous instance had set value using 'this', not static , default properties of objects inside should show up. i have created above example demo. i'm facing issue in library. know has objects stored reference. how should proceed expected output? thoughts? you move prototype property (which instances identical) object
