HOW

ゴール: Hex and base64 encoding decoding, searching, and byte length calculation with bare-buffer
パッケージ: bare-buffer 3.7.0
シンボル: Buffer.byteLength
Buffer.isEncoding
Buffer.prototype.fill
Buffer.prototype.includes
Buffer.prototype.indexOf
環境: node 22.23.2
作成日: 2026-08-26T14:11:39Z

Buffer.isEncoding returns true for standard encodings and false for unsupported formats
Buffer.byteLength calculates exact byte sizes for utf8, hex, and base64 encoded strings
Buffer.from and toString convert accurately between binary buffers and hex strings
Buffer.from and toString convert accurately between binary buffers and base64 strings
fill populates buffer ranges with numeric byte values and repeated string patterns
indexOf finds first occurrence offset of byte values, strings, and buffers
includes checks whether a buffer contains a specific sequence or byte value
indexOf returns -1 and includes returns false when target pattern is not present
