My TypeScript config contains:
"target": "es5",
"lib": [
"es2020",
"dom"
]
Still, there are some modern features like Array.prototype.includes and Object.entries that are not transpiled at all. Why is that?

1The `target` only transpiles to compatible *syntax*, it doesn't add methods and other API stuff. You would need to polyfill those. – VLAZ Jun 18 '20 at 21:11
