Binary00001100
A = 00111100
B = 00001101
R = 00001100

Calculation steps

  1. 1A = 60 = 00111100(2); B = 13 = 00001101(2)
  2. 2Operation: & — 按位与（两位都 1 才得 1）
  3. 3Result = 12 = 00001100(2) = 0xC
JavaScript bitwise ops convert operands to signed 32-bit integers — for 64-bit use BigInt (0n & 1n). Common uses: flags/permissions (1<<n), RGB packing ((r<<16)|(g<<8)|b), hash mixing, fast ×2/÷2 shifts. XOR swap and ~A = −A−1 are classic interview traps.
