Creating an IF like statement depending on the status of the task JS React

I am getting info on tasks from my backend with JSON values of "isDone: false"

I would like some sort of an IF statement for the image that appears depending on whether the task is done.

return (
    <Card
      {...rest}
      className={clsx(classes.root, className)}
    >
      <CardContent>

        <div className={classes.imageContainer}>
          <AccessTimeIcon className={classes.}/>

        </div>

</div>

if the task is not done i want to show classes.doneIcon

How is this possible for me inside my return component?

Thanks!
