what is an API?
An API stands for "Application Programming Interface". It's a way for two different programs, or software components, to communicate with each other. APIs define the protocols and rules for how one component should interact with the other. For example, a web application might use an API to fetch data from a database, or to get the latest weather forecast from a weather service. APIs can be used in many programming languages, but some common formats include REST and GraphQL. You can find more information on APIs in this article: https://www.smashingmagazine.com/2018/01/understanding-using-rest-api/ (written in JavaScript).
👩💻 can you explain what an API is like i'm 8?
Sure, I'd be happy to! Imagine you have a toy box with lots of different toys in it. You want to play with your friend, but your friend is not with you right now. However, your friend calls you and asks if they can play with some of your toys.
An API is like the way you and your friend talk over the phone. You tell your friend what toys they can play with, and how they can play with them. Similarly, an API allows two different computer programs to talk to each other and work together, just like you and your friend played with toys together. With an API, one program can request data or services from another program, and the API will send back the requested information.
👩💻 what are some examples of an API?
Here are some examples of APIs:
There are many more APIs available for developers to use, and they cover a wide variety of topics and services.
show thw weather forecast for one day using API with React
The first step is to find an API that provides the necessary data. A good place to start is OpenWeatherMap, which provides a free API that offers specific API calls for retrieving current and forecast weather data.
After signing up for an API key and getting the API call from OpenWeatherMap, the next step is to write a React component to make the API call. This can be done using JavaScript's fetch API method.
Below is a simple example of a React component named MyWeatherComponent which requests current weather data for one day and displays it in the DOM.
js Copy code
import React, { Component } from "react";
const API_KEY = "<INSERT_OPENWEATHERMAP_API_KEY_HERE>";
class MyWeatherComponent extends Component {
state = {
weatherData: ""
};
componentDidMount() {
this.fetchWeatherData();
}
fetchWeatherData = () => {
fetch(
`http://api.openweathermap.org/data/2.5/weather?q=London,uk&appid=${API_KEY}`
)
.then(res => res.json())
.then(data => {
this.setState({
weatherData: data
});
});
};
render() {
return (
<div>
{this.state.weatherData.name}
{this.state.weatherData.main.temp}
</div>
);
}
}
export default MyWeatherComponent;
This example fetches the current weather data for London, but with a few modifications it can be used to fetch a forecast for one day. It is also possible to modify the API call to get weather data for a city other than London.

AI stands for Artificial Intelligence. AI bots are able to learn from conversations with users and expand their knowledge this way.
SheCodes Athena will help you with technical questions about your code using artificial intelligence to find the answer. Imagine a super powerful human who has memorized everything on the internet and can access that knowledge in a matter of seconds. 🤯
SheCodes Athena can answer most coding-related questions, even complicated ones! It can even find bugs in your code and tell you how to fix them in just a few seconds. Impressive, right?
Just remember we're still in testing mode so the AI may return strange or incorrect replies. Feel free to message us if this happens!
SheCodes Athena can only reply to coding-related technical questions. The same type of questions you would ask in the channels on Slack.
For questions that are not coding-related, write us here 😃
You should treat Athena like a SheCodes team member, so always be polite! 😊 Ask your questions as detailed as possible, just like you would do on Slack.
Here are some examples:
- Prettier isn't working on my VS Code. How do I fix this?
- How do I make bullet points with different colors using the list element?
- My code in Codesandbox is having some issues. Can you please tell me what the issue is? [Include the link to your Codesandbox]
For now, SheCodes Athena is limited to 5 questions per day for each student.
In that case, you can either ask SheCodes Athena a follow-up question, or you can post on the designated weekly channel on Slack!
Our technical assistants are still available on Slack and are always happy to help! 😍💪
Remember, questions are limited to 1000 characters.
- If you're working with an HTML file: Post a snippet of your code related to the issue you're having (just copy the code and paste it into the question box).
- If you're working with Codesandbox: Good news, you can just post the link to your Codesandbox and the AI Assistant will be able to view your code.
- If you have a longer question that would require an entire HTML file or more than 1000 characters, post it in the designated weekly channels on Slack! 😃
Athena was the Greek goddess of wisdom, among other elements. She received her name from the city of Athens, which she is known for protecting.
Much like the goddess Athena, SheCodes Athena is also incredibly wise and can solve complicated coding puzzles in a matter of seconds! 😍
Not likely. AI can automate tasks and make developers' jobs more efficient but it can't fully replace the human ability to deal with complex software. And AI will still require human developers to supervise and improve it further.
So developers may see their tasks change but they won't be replaced by AI. 👩💻🤝💻
