The Controller we have made can be instantiated and used using controller as Syntax. That's because we have put variable directly on the controller class and not on the $scope. Using controller as someName is to seperate the controller from $scope itself.So, there is no need of injecting $scope as ...

The way the $scope is injected in the controller's constructor functions is a way to demonstrate and use the basic option of angular dependency injection but is not production ready as it cannot be minified. Thats because the minification system changes the variable names and anguar's dependency i...

Use try-finally to avoid leaking resources (such as memory) in case an exception occurs during execution. The procedure below saves a string in a file and prevents the TStringList from leaking. procedure SaveStringToFile(const aFilename: TFilename; const aString: string); var SL: TStringList; ...

An array is just a block of sequential memory locations for a specific type of variable. Arrays are allocated the same way as normal variables, but with square brackets appended to its name [] that contain the number of elements that fit into the array memory. The following example of an array uses...

Const baseString As String = "Foo Bar" Dim leftText As String leftText = Left$(baseString, 3) 'leftText = "Foo"

'Trim the leading and trailing spaces in a string Const paddedText As String = " Foo Bar " Dim trimmedText As String trimmedText = Trim$(paddedText) 'trimmedText = "Foo Bar"

Typical usage of ExtJS leverages the framework to build single-page rich-applications (RIA). The simplest way to get started is to make use of Sencha Cmd, a CLI build tool covering most of the general concerns in a deployment life-cycle, primarily: package and dependency management code compil...

Used by awk to separate fields output by the print statement. For example: echo "a b c d e f" | awk 'BEGIN {OFS="-"} {print $2, $3}' produces: b-c e-f The default value is , a string consisting of a single space.

Command line arguments passed to awk are stored in the internal array ARGV of ARGC elements. The first element of the array is the program name. For example: awk 'BEGIN { for (i = 0; i < ARGC; ++i) { printf "ARGV[%d]=\"%s\"\n", i, ARGV[i] } }' arg1 arg2 arg3 ...

Aside from destructuring objects into function arguments, you can use them inside variable declarations as follows: const person = { name: 'John Doe', age: 45, location: 'Paris, France', }; let { name, age, location } = person; console.log('I am ' + name + ', aged ' + age + ' and li...

There is currently a proposal (not yet part of the ECMAScript standard) to add a finally callback to promises that will be executed regardless of whether the promise is fulfilled or rejected. Semantically, this is similar to the finally clause of the try block. You would usually use this functional...

We often encounter a situation where a property we're trying to extract doesn't exist in the object/array, resulting in a TypeError (while destructuring nested objects) or being set to undefined. While destructuring we can set a default value, which it will fallback to, in case of it not being found...
