"modern environments" meaning if you're shipping un-transpiled code, this will work on 93% of browsers. See full compatibility at caniuse.com/…

[...document.querySelectorAll("*")].filter(e => e.childNodes && [...e.childNodes].find(n => n.nodeValue?.match("❤")))

Super modern one-line approach with optional chaining operator

You really don't need underscore/lodash for this ... nowadays anyways

Microbundle also outputs a modern bundle specially designed to work in all modern browsers. This bundle preserves most modern JS features when compiling your code, but ensures the result runs in 90% of web browsers without needing to be transpiled. Specifically, it uses preset-modules to target the set of browsers that support <script type="module"> - that allows syntax like async/await, tagged templates, arrow functions, destructured and rest parameters, etc. The result is generally smaller and faster to execute than the esm bundle
