    and call addEventListener with click and a function.

    and lets me remove the listener later.

  3. 3
    Inline onclick mixes behavior

    into HTML and is harder to test.

  4. 4
    Give an example

    One tiny concrete case you can say aloud.

  5. 5
    Common mistake

    What juniors usually get wrong.

  6. 6
