    here's what it solves.

    before:

    let myEl = document.querySelector('.my-elem') ? document.querySelector('.my-elem').innerHTML : null;

    after:

    let myEl = document.querySelector('.my-elem')?.innerHTML

    my life is changed forever.

    Yup, it's awesome. Small correction - if not finding the chained thing, it will return undefined, not null.

    the correct search term for this is "null-safe property access"
