Show HN: JavaScript by Example

Hi all. I built this simple website of JavaScript built-in features to achieve these goals:

- serve as the reference for JS developers, reduce the amount of time taken googling how to use them and browsing through long MDN docs

- provide a documentation that has guaranteed correctness for the JS example execution result (using eval)

Any feedback is welcomed! (Should have posted this earlier)

Cool stuff! slice always confuses me. The one example that results in ‘banana’ I had to look twice.

Would be nice to also mention function parameters and a “randomize” button. See for example the playground API of DataGridXL (https://datagridxl.com/api/methods)
