Falsehoods programmers believe about time

This is a compiled list of falsehoods programmers tend to believe about working with time.

Don't re-invent a date time library yourself. If you think you understand everything about time, you're probably doing it wrong.

Falsehoods

• There are always 24 hours in a day.
• February is always 28 days long.
• Any 24-hour period will always begin and end in the same day (or week, or month).

  const chunks: Array<any> = [];
  for await (let chunk of stream) {
      chunks.push(chunk)
  }
  const buffer = Buffer.concat(chunks);
  return buffer.toString("utf-8")
}
