Deciphering IntelliSense:

IntelliSense encompasses a range of code editing features like code completion, parameter info, quick info, and member lists. Often referred to as ‘code completion’, ‘content assist’, or ‘code hinting’, IntelliSense is designed to streamline your coding experience.

But, IntelliSense is also an feature in many IDEs, including Visual Studio and Visual Studio Code, that provides code completion, parameter info, quick info, and member lists.

How IntelliSense might be programmed (Based on my Limited understanding)

1. Language Service: At the core of IntelliSense will be a language service. This service analyzes the code you write and provides intelligent code completions based on the language’s semantics and the context of your code.

3. Trigger Characters: IntelliSense is often triggered by specific characters, like a period (.) in many languages. When you type these characters…
