RAG from Scratch

Demystify Retrieval-Augmented Generation (RAG) by building it yourself - step by step.
No black boxes. No cloud APIs. Just clear explanations, simple examples, and local code you fully understand.

This project follows the same philosophy as AI Agents from Scratch:
make advanced AI concepts approachable for developers through minimal, well-explained, real code.

Setup Data Analysis Environment with Typescript

Similar to Pandas & Jupyter Notebook in Python

In this tutorial we will set up an environment to make data analysis with typescript and write our code in an experimental environment like Jupyter Notebook.

The following part is copied from https://github.com/yunabe/tslab.

	/**
	* Exercise 1: Build a Multiplier Runnable
	*
	* Goal: Create a Runnable that multiplies numbers by a factor
	*
	* Requirements:
	* - Takes a number as input
	* - Multiplies by a factor set in constructor
	* - Returns the result
	*
