8,714 Pointsi is only returning 6. What's going on?
Hi, I'm working through the practice state in react challenge. Video 3, I can't get the solution to work. The state only updates to 5, it doesn't update to any other value. I've been looking around and I can't figure out what's going on. Below is the function I've created and then under that is the component it's passed to in props.
createStarComponents = () => {
var starArray = [];
var maxRating = 5;
for ( var i = 0; i < maxRating; i ++ ) {
starArray.push(
<Star
starHandler={ () => this.starHandler( i ) }
key={i}
/> );
}
return starArray;
}
const Star = (props) =>
// 1. Call the function that updates the rating state each time a list item is clicked
// 2. Give the <li> the class 'selected' if it's one of the selected stars
<li onClick={props.starHandler}>
<svg x="0px" y="0px"
viewBox="0 0 16 15" className="star" >

8,714 PointsHi Clayton, thanks for your comment. I also tried it without maxRating and just declaring i n the for loop and still have the same problem
