Contract
- ms parses duration strings with various units to milliseconds
- ms parses decimal and negative duration strings to milliseconds
- ms formats millisecond values to concise short string format
- ms formats millisecond values to human-readable long string format when options.long is true
- ms formats negative millisecond values with leading negative sign
- ms returns undefined for invalid unparseable duration strings
- ms throws TypeError or Error when input is not a non-empty string or number
