Zero to Document Hero - Intro to MongoDB and .NET

Heard about Document Databases and MongoDB but wondered what it is about? Tried NoSQL in the past and not been able to get your head around the differences with SQL and relational databases? In this talk I break down the differences and also look at how well it works with .NET development with added AI content!

Strings

`String.prototype.*`

None of the string methods modify this – they always return fresh strings.

charAt(pos: number): string ^ES1

Returns the character at index pos, as a string (JavaScript does not have a datatype for characters). str[i] is equivalent to str.charAt(i) and more concise (caveat: may not work on old engines).

Directory structure for JavaScript/Node Projects

While the following structure is not an absolute requirement or enforced by the tools, it is a recommendation based on what the JavaScript and in particular Node community at large have been following by convention.

Beyond a suggested structure, no tooling recommendations, or sub-module structure is outlined here.

Directories

lib/ is intended for code that can run as-is
src/ is intended for code that needs to be manipulated before it can be used
