In 2016 Alexander Kallaway created a 100daysOfCode challenge to help him to achieve his goal as a software developer. Since then thousands of developers have undertaking the challenge and it even has become a trend in social media.
The purpose of the challenge is simple – to build a strong and consistent coding habit. Thats why the challenge follows one simple rule – you need to code for at least 1 hour each day for the next 100 days. There is a guideline and set of rules you need to follow during the challenge and they are mostly to keep you focused on your goal. And I am going to try it 🙂
Here are my goals for this challenge:
- to get more practice and learn new things
- to improve my discipline and set myself up for success
- to build coding habit
- to create a strong portfolio
Each day I am going to make changes to this blog with a progress I made. I will post links to my projects on CodePen or Github and i would really appreciate your feedback about what can be improved or done in another way, what looks good and what looks bad. Good luck to me! 🙂

introduction to react
React (also known as React.js or ReactJS) is a JavaScript library for building user interfaces. It is maintained by Facebook and a community of individual developers and companies.
React can be used as a base in the development of single-page or mobile applications. However, React is only concerned with rendering data to the DOM, and so creating React applications usually requires the use of additional libraries for state management and routing.
So my next coding experience would cover this topic.

Day 52: April 20, 2020
React
Today’s Progress: Today I started to build Star Match Game from react course at Pluralsight. First I wrote static markup in JSX and logic in JavaScript (all functions for the game). Then I had to extract reusable components from that. So instead of one main component I ended up with 3 components. After that I worked with view functions – to reflect state on the UI. Such an exercise is truly teaches you a lot! https://codesandbox.io/s/the-star-match-game-ezl6d?file=/src/StarMatch.js
Day 53: April 21, 2020
React
Today’s Progress: Continued to build Star Match Game from react course at Pluralsight.

Day 54: April 22, 2020

Day 62: April 30, 2020
React
Today’s Progress: Today I watched video tutorial on PluralSight about building quiz with React components. It had different approach of adding props. Instead of adding all props to the component (f.ex const Author =(props)=>{}), the guy added specified props (f.ex const Author =({title, books})=>{})….to me passing just props is more convenient Example here: https://codesandbox.io/s/authorquiz-z39pz?file=/src/AuthorQuiz.js
Day 63: May 1, 2020
React
Today’s Progress: Today I created a small online game – Author Quiz using React to practice the knowledge I already have. Link to project here: https://codesandbox.io/s/authorquiz-z39pz?file=/src/AuthorQuiz.js

React
Today’s Progress: Today I was working under data tree project, mainly with styling. I added:
- caret class to the parent and implemented change of classes dynamically
- if parent has children, caret is pointing to the right
- if parent is open, caret is pointing down
- started implementation of showing JSON object when you click on tree node
Day 69: May 7, 2020
React
Today’s Progress: Today I learned how to create Form in React. I have added a simple form to the Author Quiz game and I learned:
- how to bind value of the input to component state
- how to handle onChange and onSubmit events
Day 70: May 9, 2020
React
Today’s Progress: Today I was working under data tree project. I learned how to pass data from one child component to another child component using parent as intermediate 🙂 I was really surprised I could implement that correct from first try.
Day 71-72: May 10-11, 2020
React
Today’s Progress: Continued to work under data tree project. Added some light styling, added some reusable components which Im planning to use in the future components – you can see them on the right side of page – its Path, Arguments, Errors and Artefacts. Now it is super easy to combine them and form new component to display a tree node.
Day 73: May 12 , 2020
JavaScript
Today’s Progress: Today I read about React props but was not coding anything. I was chilling with Java Script algorithms instead…..well, I would not call that real “chilling” as sometimes challenges were pretty difficult. Working my way to JS certificate on freeCodeCamp

- fractional units (fr) – grid-template-columns: 1fr – it defines how much free space the column would take
- repeat() – its repeats what size we want and how many times (grid-template-columns: repeat(4, 1fr);
Day 80: May 19, 2020
CSS
Today’s Progress: Today i continued working with CSS Grid, i learned so far:
