using react Inside of your ‘App’ class ‘render’ method, return a div with your basic information for example name, number, date of birth and etc. This div should be hard-coded
Sure! In React, inside the render method of the App class, you can return a div with your basic information. This div should be hard-coded, meaning that you can directly write the information inside the div tags without using any variable or dynamic content.
Here's an example of how you can achieve this:
jsx Copy code
import React, { Component } from 'react';
class App extends Component {
render() {
return (
<div>
<h1>Name: John Doe</h1>
<p>Number: 1234567890</p>
<p>Date of Birth: January 1, 2000</p>
</div>
);
}
}
export default App;
In the above code, the render method returns a div with a heading for the name, and paragraphs for the number and date of birth. You can replace the placeholder values with your actual information.
Please note that this is just a basic example and you can customize it according to your needs.
👩💻 Create a ‘constructor’ that takes in ‘props’ , call the ‘super()’ method, and set ‘this.state’ to an empty object inside of the ‘App’ class. Inside of ‘this.state’ create a ‘person’ property and set it to an empty object
Certainly! In React, to create a constructor that takes in props, call the super() method, and set this.state to an empty object inside the App class, you can use the following code:
jsx Copy code
import React, { Component } from 'react';
class App extends Component {
constructor(props) {
super(props);
this.state = {
person: {}
};
}
render() {
// Your component's JSX goes here
}
}
export default App;
In the above code, the constructor method is defined within the App class. It accepts the props parameter and calls super(props) to initialize the parent class (Component). Then, it sets the initial state of the component by assigning an empty object to this.state.person.
Remember to replace the comment Your component's JSX goes here with your actual component JSX code.
By setting the initial state to an empty object, you can easily update the person property with additional data later on as your application needs.
👩💻 Replace all of the hard-coded with data from ‘this.state.person’ in the constructor. Then take the returned ‘div’ and create a component, pass state into it and import it as ‘BasicInfo’.
Certainly! Let's update the code to replace the hard-coded data with data from this.state.person in the constructor. We will then create a new component, pass the state into it, and import it as BasicInfo. Here's the updated code:
jsx Copy code
import React, { Component } from 'react';
// BasicInfo component
const BasicInfo = ({ person }) => {
return (
<div>
<h1>Name: {person.name}</h1>
<p>Number: {person.number}</p>
<p>Date of Birth: {person.dateOfBirth}</p>
</div>
);
};
class App extends Component {
constructor(props) {
super(props);
this.state = {
person: {
name: 'John Doe',
number: '1234567890',
dateOfBirth: 'January 1, 2000'
}
};
}
render() {
return <BasicInfo person={this.state.person} />;
}
}
export default App;
In the above code, I've created a new functional component called BasicInfo. Inside BasicInfo, we receive the person prop and render the name, number, and date of birth using {} to access the corresponding values from person.
In the App component's render method, we are now returning the BasicInfo component and passing the person object from this.state as a prop.
Make sure to update the data in this.state.person with your actual information.
Hope that helps!
👩💻 Now that you have a basic react app to display one person’s worth of information, now modify the app to iterate over an array of people’s basic information, while still keeping the new list of contacts in the top-level of state.
Of course! To modify the app to iterate over an array of people's basic information while keeping the new list of contacts in the top-level state, we can update the code as follows:
jsx Copy code
import React, { Component } from 'react';
// BasicInfo component
const BasicInfo = ({ person }) => {
return (
<div>
<h1>Name: {person.name}</h1>
<p>Number: {person.number}</p>
<p>Date of Birth: {person.dateOfBirth}</p>
</div>
);
};
class App extends Component {
constructor(props) {
super(props);
this.state = {
contacts: [
{ name: 'John Doe', number: '1234567890', dateOfBirth: 'January 1, 2000' },
{ name: 'Jane Smith', number: '9876543210', dateOfBirth: 'February 2, 2001' },
// Add more people as needed
]
};
}
render() {
return (
<div>
{this.state.contacts.map((person, index) => (
<BasicInfo key={index} person={person} />
))}
</div>
);
}
}
export default App;
In the updated code, the contacts property in the state is an array that holds multiple objects representing each person's basic information. In the render method of the App component, we use map to iterate over the contacts array. For each person, we render the BasicInfo component and pass the individual person object as a prop.
The key={index} prop is used to uniquely identify each item in the iteration, improving performance and helping React manage updates efficiently.
Feel free to add more people and their information to the contacts array as needed.
With this modification, the app will dynamically render all the people's basic information stored in the contacts state array.

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. 👩💻🤝💻
