Good to know: Engagement rate = (likes + comments + shares + saves) ÷ followers (or reach) × 100. “By reach” is fairer because not every follower sees each post.

Words to know

Engagement rate
How many people interacted (liked, commented, shared, saved) compared to how many followed or saw the post.

Reach = how many different people saw your post. Impressions/views = how many times it was seen in total.
JSX / React
React apps write HTML-like code called JSX inside JavaScript, with small differences (className instead of class).
