Strings

String.prototype.*

None of the string methods modify this – they always return fresh strings.

  • charAt(pos: number): string ES1

    Returns the character at index pos, as a string (JavaScript does not have a datatype for characters). str[i] is equivalent to str.charAt(i) and more concise (caveat: may not work on old engines).

Install Mongo with WSL for Windows.

Home

This doc will guide you through installing Mongo DB using WSL through the Command Line.

Most of the steps are listed out here, but this guide will trim them down and make it more straight forward for our needs. There is also 1 step that is not in the link above as well, which will be noted when we come across it.

Install MongoDB Community Edition.

  1. Follow the directions listed on the mongodb official website for your distro of choice.
import PropTypes from 'prop-types';
type Omit<T, K> = Pick<T, Exclude<keyof T, K>>;
type Defined<T> = T extends undefined ? never : T;
/**
* Get the type that represents the props with the defaultProps included.

* Alternatively, we could have done something like this:

Code to stop following those ones who are not following you back on Twitter and keeping those you want or follow anyone you want, with certain filters (working in July 2019)
/*
Unfollow (stop following) those people who are not following you back on Twitter (or unfollow everyone if desired).
This will work for new Twitter web site code structure (it was changed from July 2019, causing other unfollow-scripts to stop working).
Instructions:
1) The code may need to be modified depending on the language of your Twitter web site:
* For English language web site, no modification needed.
* For Spanish language web site, remember to set the 'LANGUAGE' variable to "ES".
* For another language, remember to set the 'LANGUAGE' variable to that language and modify the 'WORDS' object to add the words in that language.
