HOW

Buffer.prototype.copy copies full byte content from source buffer to target buffer and returns bytes copied
Buffer.prototype.copy respects targetStart offset when writing into target buffer
Buffer.prototype.copy copies a slice of source buffer using sourceStart and sourceEnd offsets
Buffer.prototype.copy truncates copied bytes when target remaining capacity is smaller than source range
Buffer.prototype.copy performs in-place overlapping memory copy when source and target are the same buffer
Buffer.prototype.copy returns 0 without modification when sourceEnd is less than or equal to sourceStart
Buffer.prototype.copy returns 0 when targetStart exceeds target buffer length
