What I learned

There are many ways of adding classes in React conditionally. A great resource detailing them is provided in Useful resources section. One of the said methods is using an array and join() method:

function myComponent() {
  const classes = []
  if (isError) {
    classes.push('error')
  } else if (isWarining) {
    classes.push('warning')
  } else if (isInfo) {
    classes.push('info')
  } else {
    const indexOfError = searchBarClasses.indexOf('error')
    const indexOfWarning = searchBarClasses.indexOf('warning')
    const indexOfInfo = searchBarClasses.indexOf('info')
    searchBarClasses.splice(indexOfError - 1, 1)
    searchBarClasses.splice(indexOfWarning - 1, 1)
    searchBarClasses.splice(indexOfInfo - 1, 1)
  }

  return (
    <article className={`base-style` + ' ' + classes.join(' ')}>
      <h2>This is my component</h2>
      <p>
        Here is some info aobut it. This component was created using React. The
        classes it uses are added conditionally with an array and join() method
      </p>
    </article>
  )
}

I decided to use an empty array and have some classes for my component by default. This is because the ones I was using were for basic styling, so whole thing looked really ugly for a split second while loading when the said classes were missing. Yet you can have some items in the array if appropriate. While the article I've learnt this from doesn't really show that, you also need to make sure to remove the classes, when they're no longer needed.
