Variable Attributes in JSX

When writing JSX, it’s common to use variables to set attributes.

Here’s an example of how that might work:

// Use a variable to set the `height` and `width` attributes:

const sideLength = "200px";

const panda = (

<img

src="images/panda.jpg"

alt="panda"

height={sideLength}

width={sideLength} />

);

Notice how in this example, the <img />‘s attributes each get their own line. This can make your code more readable if you have a lot of attributes on one element.

Object properties are also often used to set attributes:

const pics = {

panda: "http://bit.ly/1Tqltv5",

owl: "http://bit.ly/1XGtkM3",

owlCat: "http://bit.ly/1Upbczi"

};

const panda = (

<img

src={pics.panda}

alt="Lazy Panda" />

);

const owl = (

<img

src={pics.owl}

alt="Unimpressed Owl" />

);

const owlCat = (

<img

src={pics.owlCat}

alt="Ghastly Abomination" />

);

Instructions

1.On line 7, declare a new variable named gooseImg. Set its value equal to a JSX <img /> element.

Give the <img /> an attribute with a name of src. Set the attribute’s value equal to the variable goose.

2.Use ReactDOM.render() to render gooseImg.

ReactDOM.render()‘s first argument should be gooseImg.

ReactDOM.render()‘s second argument should be document.getElementById('app').

app.js

import React from 'react';

import ReactDOM from 'react-dom';

const goose = 'https://content.codecademy.com/courses/React/react_photo-goose.jpg';

// Declare new variable here:
