JS Programming in C# – Objects on the fly

Creating objects without defining types is considered a great flexibility in JavaScript. JavaScript treats objects nothing more than key-value pairs. Yeah, you can declare functions in the object but they are still part of the key-value philosophy. Bottomline: JavaScript did not start out as an object oriented language.

Typically, objects are created on the fly1 using the object literal syntax:

let obj = {
   name: "Will",
   age: 26
};

There are scenarios when creating objects on the fly is indeed a flexibility.

Problem Reduction

Problem Reduction is what I call when a given problem can be expressed in terms of or solved using a solution to an alternate problem.

Take for instance, the word distance problem: Find the shortest distance between two words in a given set of words. Following is an unanimous solution, I suppose:

Importance of Semantics

Semantics is ever more important in programming.

JINQ

In his talk at the CppCon 2014, Bjarne Stroustrup explained, politely and brilliantly, how to write succinct expressive yet intent-ful code. The task is especially hard when there are parties interested in trolling1 rather than contributing. Like Stroustrup explains back, it is difficult to find the real meaning out of a large block of (legacy) code.

Getting reminded of the reminder !!!

I have been using Android for quite some time now, and only recently I noticed that Android pops up a notification reminding you of a reminder. It says “Upcoming alarm – Buy Milk”, where Buy Milk is the reminder I had set.

Is it smart enough to help a lazy volatile minded guy like me or is it trying to be my wife who would not rest until I buy milk? Don’t know.

jqGrid: Handling array data !!!

This post is primarily a personal reference. I also consider this a tribute to Oleg, who played a big role in improving my understanding of the jqGrid internals – the way it handles source data types, which, if I may say, led him in discovering a bug in jqGrid.
