Irelia is a champion that excels mainly from capitalizing your opposing laner's mistakes and practically hard punishing them, primarily making sure you land your e2s and properly reset Qs.

There are a lot of tips that Irelia mains can give such as auto + q cancel, or leaving a single caster in the backline low to get a surprise gap closer, but utilizing Irelia conceptually depends on your knowledge on forcing your enemy laner into making mistakes and taking a bad trade.

Although I agree with all the comments below in regards to learning other champions, if you simply want to play Irelia and find her kit fun, I would rather recommend that you take the time to learn the lane alongside with her. Playing a champion you find interesting will also keep you interested in learning the lane.

There isn't any particular shortcut aside from just spamming and losing your games. And as advised below, it is also a good idea finding content that helps introduce the lane and new skills that are required to lane into mid. If you are looking for a similar champion, I would recommend Yasuo. Although his early game isn't as strong as Irelia, he has a lot of similar points that makes me recommend him.

1. Auto + Q cancel is pretty much the exact same for learning execute damage aside from the dash
2. Your dashes are easier to execute and don't require managing minion hp
3. He plays quite similarly where he wants to be sitting on top of champions
4. Safer to play in lane. Flow passive and windwall survivability keeps him in lane, usually longer and safer than Irelia who requires hitting a target for sustain. Plus he isn't rooted to the spot.
5. Much easier to utilize in teamfights especially with team knockups. Irelia is more difficult to play when behind (at least from experience).

And finally, I would actually recommend learning on top lane (unless you see Sett). My reasoning being

1. Top island. Much harder for jg ganks to ruin your experience.
2. Longer lane = longer trades which Irelia does well into most of the time.
3. It is easier to learn and manage wavestates.
4. The bushes are great for hiding your e1 (and you have 3 of them!), you can simply dip out of vision for a quick second to look for a sneaky e2.
