Galal: asynchronous-programming-3 weeks

[galalkoro98]

Learning Objectives

• 🥚 You understand the JavaScript Event Loop, and can demonstrate this by using setTimeout and setInterval to schedule simple tasks.
• 🥚 You can explain why Asynchronous Programming is important for programs that have blocking and non-blocking tasks.
• 🥚 You can explain the basics of the Client/Server model and HTTP requests and can fetch data from RESTful APIs.
• 🐣 You can break down an asynchronous problem into smaller tasks and solve it using promises. This includes identify which tasks depend on each other and which are independent:
  • dependent tasks: The return value from one task is required to start the next task, these must be completed in a specific order - .then
  • independent tasks: These tasks do not use each other's return values, they can be completed at the same time - Promise.allsystem.
• 🐣 You can fetch data from an API and render it into the DOM using /api-calls, /handlers and async/await syntax.
• 🐣 You can write unit tests for functions that return promises using async/await syntax.

Week 3

• [x] I have pushed my progress to my fork repo
• [x] I have push my week project progress to the repo

I Need Help With:

Yes I do need help with my week project which I have problem in back-end app

const fs = require("fs"); const express = require("express"); const app = express(); const PORT = process.env.PORT || 5000;

app.use(express.static(__dirname + "/")); app.use(express.json());

app.get("/getTasks", (req, res) => { const data = JSON.parse(fs.readFileSync("db.json")); console.log(data); res.json(data); });

app.post("/saveTask", (req, res) => { const data = req.body; fs.writeFileSync("db.json", JSON.stringify(data)); res.json({ status: "saved" }); });

app.listen(PORT, () => { console.log("Server is running on port " + PORT); });

What went well?

fetch

What went less well?

week project went kind a approch to the point just need some feedback

Lessons Learned

• What is sychornous and Asychronous
• fetch with GET, POST and & DELETE methods
• Simple back-end

Hi @galalkoro98 Great progress so far!

Perhaps I can help with the implementation that you need to perform. Feel free to reach out via Slack :)
