• Similar to strim but more performant.
• BOTH, LEFT, RIGHT, DEFAULT are strings and may be "".
• Chars in BOTH are trimmed from left and right ends of STR.
• Chars in LEFT/RIGHT are trimmed from the respective end of STR.
  • By default, chars in BOTH/LEFT/RIGHT are in addition to "\n", "\t" and " ".
• Chars in DEFAULT replace the default trim chars.
