Try catch Errors must always be handled. If you are using synchronous programming you could use a try catch. But this does not work if you work asynchronous! Example: try { setTimeout(function() { throw new Error("I'm an uncaught error and will stop the server!"); }, 1...

Progress supports one dimensional arrays, but they are called EXTENTS. /* Define a character array with the length 5, and display it's length */ DEFINE VARIABLE a AS CHARACTER EXTENT 5 NO-UNDO. DISPLAY EXTENT(a). Individual positions i the array is accessed using "standard" c-style b...

You can create classes without names that are not installed in the system by sending newAnonymousSubclass to a class. For example anonymousSet := Set newAnonymousSubclass will assign an anonymous subclass of Set to anonymousSet variable. Then you can compile methods in this class and instantiat...

Consider the Binary Tree: Pre-order traversal(root) is traversing the node then left sub-tree of the node and then the right sub-tree of the node. So the pre-order traversal of above tree will be: 1 2 4 5 3 6 7 In-order traversal(root) is traversing the left sub-tree of the node then the node ...

Consider the tree: Lowest common ancestor of nodes with value 1 and 4 is 2 Lowest common ancestor of nodes with value 1 and 5 is 3 Lowest common ancestor of nodes with value 2 and 4 is 4 Lowest common ancestor of nodes with value 1 and 2 is 2

One of the ways to think about the commands that should be executed, to edit a text in a certain manner, is as entire sentences. A command is an action performed on an object. Therefore it has a verb: :normal i " insert :normal a " append :normal c " overwrite :normal y ...

An anonymous function can be defined without a name through a Lambda Expression. For defining these type of functions, the keyword lambda is used instead of the keyword defun. The following lines are all equivalent and define anonymous functions which output the sum of two numbers: (lambda (x y) (...
