Introduction

React Native makes it possible to make native iOS and Android mobile apps without needing to know any iOS or Android programming - just JavaScript!

In this course, we'll write a simple mobile app that you can run on your own phone and share with your friends!

Prerequisites

In order to take advantage this course, you should have the following experience.

winhc

void main() {
  String url =
      "https://www.rbdmyanmar.com/product/kiwi-colour-shine-protect-liquid/?attribute_pa_color=brown&attribute_pa_net-content=75ml&attribute_pa_pack-size=24-pcs"; 

  int urlIndex = url.indexOf('?');
  print('? index => $urlIndex');

  String newUrl = url.substring(urlIndex + 1, url.length);
  print('newUrl => $newUrl');

Handling Multiple Github Accounts on MacOS

The only way I've succeeded so far is to employ SSH.

Assuming you are new to this like me, first I'd like to share with you that your Mac has a SSH config file in a .ssh directory. The config file is where you draw relations of your SSH keys to each GitHub (or Bitbucket) account, and all your SSH keys generated are saved into .ssh directory by default. You can navigate to it by running cd ~/.ssh within your terminal, open the config file with any editor, and it should look something like this:

Host *
 AddKeysToAgent yes

> UseKeyChain yes

Activate MS Office 2019/2016 for macOS - Microsoft_Office_2019_VL_Serializer

Office 2019 above

2019-06-03

Note that Office2019 DO NOT support activate via simple copy/paste plist license file which is the simplest way to activate Office 2016. Fortunately, you can also use the VL Serializer tool, just install Office 2019 and Serializer, then run Serializer to activate.
