Built with

  • Mobile-first workflow
  • TypeScript
  • React - JS library

What I learned

This was my first time using typescript in a project. Here's some of the code.

type Props = {
  day: string;
  amount: number;
  index: number;
};

function setColour(): string {
  const dayToday = new Date().getDay();
  return dayToday === index ? "hsl(186, 34%, 60%)" : "hsl(10, 79%, 65%)";
}

const height: string = `${Math.floor((amount / 70) * 100)}%`; // get dynamic heights in percentage

Continued development

Since this was my first time using typescript, I hope to build more projects using it in the future to improve my skills.
