    1. A simple rule of thumb: the name of the updated variable must appear on the left hand side of the assignment. For example this... const foo = obj.foo; foo.bar = 'baz';...won't update references to obj.foo.bar, unless you follow it up with obj = obj.

    1. Looks like the problem is that debounce defaults to waiting for 0 ms ... which is completely useless!

      It would be (and is) way to easy to omit the 2nd parameter to https://lodash.com/docs/4.17.15#debounce.

      Why is that an optional param with a default value?? It should be required!

      There must be some application where a delay of 0 is useless. https://www.geeksforgeeks.org/lodash-_-debounce-method/ alludes to / implies there may be a use:

      When the wait time is 0 and the leading option is false, then the func call is deferred until to the next tick.

      But I don't know what that use case is. For the use case / application of debouncing user input (where each character of input is delayed by at least 10 ms -- probably > 100 ms -- a delay of 0 seems utterly useless.

    1. When using React hooks there is no concept of onMount because the idea of only running some code on mount leads to writing non-resilient components, components that do one thing when they mount, and then don’t take prop changes into account.
    1. Note that if you are calling reset() and not specify new initial values, you must call it with no arguments. Be careful to avoid things like promise.catch(reset) or onChange={form.reset} in React, as they will get arguments passed to them and reinitialize your form.

    1. OK, so what about regular messages? Turns out they are not encrypted after all. Where Signal implements the security and privacy protocols right from the start, Telegram separates the two and offers an additional option. The problem is that not everyone is aware of the Secret Chat option and first-time users may send sensitive information in the regular chat window unknowingly.

    1. Remember to call super in any subclasses that override teardown.

      And yet the Rails core chose not to use RSpec, citing how it would be too easy to write subject == expected on accident?
