What I learned

I'm proud of this react component:

export const Bars = (props) => { const divisor = 7; const data = props.data; let maxValue = 0; for (let i = 0; i < data.length; i++) { if (maxValue < data[i].amount) maxValue = data[i].amount; }

const onEnter = (e) => { const element = e.target.classList; element.toggle("active"); const amountElem = document.getElementById(bar-${e.target.id});
amountElem.classList.toggle("active-amount"); }; const onLeave = (e) => { const element = e.target.classList; element.toggle("active"); const amountElem = document.getElementById(bar-${e.target.id}); amountElem.classList.toggle("active-amount"); }; return data.map((e) => { const dayStr = moment()._locale._weekdaysShort[moment().day() == 7 ? 0 : moment().day()]; const index = data.indexOf(e); return (

{data[index].amount}

{data[index].day} ); }); };

Continued development

i would like to continue develop my skills with React Hooks and react in general
