i probably just wrote some godawful react but it's also my first time writing react
react code
renderDie(num) {
// Adds a key attribute for reasons I don't really understand, but it made my js console stop complaining
return <Die key={this.state.numrendered++} num={num} />;
}
Follow
re: react code (the reason why)
if frame N has
<Die num="2">
<Die num="3">
and frame N+1 has
<Die num="2">
<Die num="3">
<Die num="3">
React doesn’t know whether to add the third Die before or after the second one, because they’re identical. adding a key just helps it figure out which Die is the new one and which one is the old.
