Azure, DevOps and .NET articles

With this article I would like to present you six useful features of the 6.0 version of C#.

null conditional operator

Removes the need for checking for null values and thus we avoid the tedious if(... != null && ... != null ...) if conditions.

  if (myDog?.Mouth?.TeethsInMouth[0]?.ScientificName == "default tooth name") ...

Highlighting your code-examples in your blog makes your articles simpler to read. When using Jekyll the “default” option for highlighting code is provided from the pygments plugin.

With this article, I want to quickly and simply explain the most important ways to convert JavaScript from one value type to another. Type casting is most often referred to as coercion. There are two types of coercion: explicit and implicit.

• Explicit coercion is usually obvious to the programmer who reads a part of JavaScript code.
• Implicit coercion is done more subtly and is not always obvious to the programmer, especially if they have not used an implicit coercion operation before.

Strings in JavaScript are immutable which means that once a string is defined, it cannot be changed anymore. Trying to change a string with a standard String-function will only create a new string and not affect the original string. Consider the following example, where the value in string1 is not changed:

var string1 = "LOREM IPSUM";
string1.toLowerCase();
console.log(string1);

Inspired from an exercise in hackerrank.com, I found the opportunity to present you the data types that JavaScript defines, which are the following six:

• undefined
• null
• number
• string
• boolean
• object

Arrays and functions are plain objects in JavaScript and they both belong to the object data type.
