> Whitespace in this context is all the whitespace characters (space, tab, no-break space, etc.) and all the line terminator characters (LF, CR, etc.).
The trimBufferStart() method return the buffer stripped of whitespace from its left end. trimBufferStart() do not affect the value of the buffer itself.
Exactly what String.prototype.trimStart() does, just for buffers.
The trimBufferEnd() method return the buffer stripped of whitespace from its right end. trimBufferEnd() do not affect the value of the buffer itself.
Exactly what String.prototype.trimEnd() does, just for buffers.
The trimBuffer() method return the buffer stripped of whitespace both ends. trimBuffer()` do not affect the value of the buffer itself.
Exactly what String.prototype.trim() does, just for buffers.
