You can manage the state for each type of challenge and toggle the PopUp only when one challenge is selected. I presume only one single challenge can be select at a time.
<!-- begin snippet: js hide: false console: true babel: true -->
<!-- language: lang-js -->
class Challenge extends React.Component {
constructor(props) {
super(props);
this.state = {
isPopped: false,
selectedChallenge: ""
}
}
selectChallenge = (challengeName) => {
this.setState({
selectedChallenge: challengeName,
});
this.togglePopped();
}
togglePopped = () => {
this.setState({isPopped: !this.state.isPopped});
}
render() {
return <div>
{this.state.isPopped && <Dialog2 challenge={this.state.selectedChallenge} hideDialog={this.togglePopped}/>}
<div className="challanges">
<h1 className="newchallenge">Choose New Challange</h1>
<button className="challangeBtn" onClick={() => {
this.selectChallenge('Eat Vegetarian (31days ')
}}>
Eat Vegetarian (31days)
</button>
<button className="challangeBtn" onClick={() => {
this.selectChallenge('Take the bike to work (14days)')
}}>
Take the bike to work (14days)
</button>
<button className="challangeBtn" onClick={() => {
this.selectChallenge('Recycle your plastic bottles (31days)')

</button>
<button className="challangeBtn" onClick={() => {
this.selectChallenge('Use public transport to commute (31days)')
}}>

</button>
<button className="challangeBtn" onClick={() => {
this.selectChallenge("Don't fly an airplane (365days)")
}}>

</button>
</div>
</div>;
}
}
class Dialog2 extends React.Component {
constructor(props) {
super(props);
}
render() {
return <div>
<h2>Dialog2</h2>
<div>{this.props.challenge}</div>
<button onClick={this.props.hideDialog}>Hide</button>

}
}

Here is the functional component version
function Challenge (props) {
const [isPopped, setIsPopped] = useState(false);
const [selectedChallenge, setSelectedChallenge] = useState("");
const selectChallenge = (challengeName) => {
setSelectedChallenge(challengeName);
togglePopped();
}
const togglePopped = () => {
setIsPopped(!isPopped);
}
return <div>
{isPopped && <Dialog2 challenge={selectedChallenge} hideDialog={togglePopped}/>}
<div className="challanges">
<h1 className="newchallenge">Choose New Challange</h1>
<button className="challangeBtn" onClick={() => {
selectChallenge('Eat Vegetarian (31days ')
}}>
Eat Vegetarian (31days)
</button>
<button className="challangeBtn" onClick={() => {
selectChallenge('Take the bike to work (14days)')
}}>
Take the bike to work (14days)
</button>
<button className="challangeBtn" onClick={() => {

}}>
Recycle your plastic bottles (31days)

<button className="challangeBtn" onClick={() => {

That's [*property spread notation*][1]. It was added in ES2018 (spread for arrays/iterables was earlier, ES2015), but it's been supported in React projects for a long time via transpilation (as "[JSX spread attributes][2]" even though you could do it elsewhere, too, not just attributes).
`{...this.props}` *spreads out* the "own" enumerable properties in `props` as discrete properties on the `Modal` element you're creating. For instance, if `this.props` contained `a: 1` and `b: 2`, then
<Modal {...this.props} title='Modal heading' animation={false}>
would be the same as
<Modal a={this.props.a} b={this.props.b} title='Modal heading' animation={false}>
But it's dynamic, so whatever "own" properties are in `props` are included.
Since `children` is an "own" property in `props`, spread will include it. So if the component where this appears had child elements, they'll be passed on to `Modal`. Putting child elements between the opening tag and closing tags is just syntactic sugar — the good kind — for putting a `children` property in the opening tag. Example:
<!-- begin snippet: js hide: true console: true babel: true -->
<!-- language: lang-js -->
class Example extends React.Component {
render() {
const { className, children } = this.props;
return (
<div className={className}>
{children}
</div>
);
}
}
ReactDOM.render(
[
<Example className="first">
<span>Child in first</span>
</Example>,
<Example className="second" children={<span>Child in second</span>} />
],
document.getElementById("root")
);
<!-- language: lang-css -->
.first {
color: green;
}
.second {
color: blue;
}
<!-- language: lang-html -->
<div id="root"></div>

Spread notation is handy not only for that use case, but for creating a new object with most (or all) of the properties of an existing object — which comes up a lot when you're updating state, since you can't modify state directly:
this.setState(prevState => {
return {foo: {...prevState.foo, a: "updated"}};
});
That replaces `this.state.foo` with a new object with all the same properties as `foo` except the `a` property, which becomes `"updated"`:
<!-- begin snippet: js hide: true console: true babel: false -->
<!-- language: lang-js -->
const obj = {
foo: {
a: 1,
b: 2,
c: 3
}
};
console.log("original", obj.foo);
// Creates a NEW object and assigns it to `obj.foo`
obj.foo = {...obj.foo, a: "updated"};
console.log("updated", obj.foo);
