Good morning, friend! It's Daniel here, the guy who manages the js-craft.io website. Hope my email finds you well!

Here at Js-Craft, February was a full month with a brand new book about React, and now with the launch of a full video course. Let's learn!

In this edition of the newsletter:

• 📘 Product updates: video lessons for the Js-Craft guide to React
• 🤔 What do you want me to work on next?
• 📰 New articles on Js-Craft
• 🍿 Coding screencasts videos
• 🌎 Cool links from around the web
• 🏝 Some non-coding things

📘 Product updates: video lessons for the Js-Craft guide to React

In February 2024 I launched my first written course: The Js-Craft Guide to React. Thanks so much to all of you who had purchased the course.

For the past two weeks, I've been heads down recording a set of video lessons for this course. You can see here two sample lessons:

• 🎬 02 - Scaffolding the basic components
• 🎬 04 - Picking a random sign

All the video lessons are now included in the basic package of the course.

You can still get the course with a special 30% discount.

For those of you who have bought the course, you can download the lessons from the Payhip account. Just reply to this email if you need any help.

🤔 What do you want me to work on next?

In March I will start the work on the next product. I have 3 ideas and want to ask you what you feel will be more helpful for you:

• 🗺 CSS Layout with Flexbox and CSS Grid; learn how to make web responsive layouts and eliminate the CSS frustration
• 🤖 Using Langchain with React; build Open AI powered apps using Javascript, create autonomous agents, or define a context for a Large Language Model
• 💸 Javascript Interview Questions: Data Structures, and Algorithms; learn how to ace your next developer interview

What format do you prefer for a course:

• 💻 I like to watch it as a video
• 📚 I like to read it as a book

Just clicking on a link it's enough to count as a vote.

📰 New articles on Js-Craft

From the past edition of the newsletter, I've written five new articles including an example of how to make your first AI-powered app with LangChain and ReactJs.

Here are all the new or updated articles:

• Example app with LangChain and ReactJs
• Langchain output parsers in Javascript
• Lessons from Software Engineering at Google – Book Review
• The pitfalls of using Index as Keys in React
• What to use as keys in React instead of the index

🍿 Coding screencasts videos

I've also added a full video tutorial for:

• How to use React to upload multiple files

🌎 Cool links from around the web

Some good content I've discovered in the past few weeks:

• Why are hyperlinks blue?
• Specificity battle
• New in Chrome 122: Storage Buckets API, DevTools Performance panel updates, and more!

🏝 Some non-coding things

We have the parents of my wife over to help with our daughter so finally some time to just do fun stuff. So, in the past few days I've been:

• 🎮 playing a lot of Virtual Fighter 5; I know, I know VF5 is old, but such a coll beat-em-up game
• 📺 watched the Genius: MLK/X tv show. Very good;

Well, that's all folks! Be smart, be kind, and keep coding!
