jsがおかしい？ 勝手に値が書き換わる配列

function brainfuck(code,iput,len){
  let p = 0;
  let m = [];
  let me = [];
  for(let i = 0; i < len; i++){
    m.push(0);
  }
  me = m;
  console.log(me);
  let output = "";
  let input_num = 0;
  let indent = 0;
  let indent_m = [];
  for(let i = 0; i < code.length; i++){
    switch(code[i]){
      case "+":
        m[p]++;
        m[p] %= 256;
      break;
      case "-":
        m[p]--;
        m[p] %= 256;
      break;
      case ">":
        p++;
        p %= len;
      break;
      case "<":
        p--;
        p %= len;
      break;
      case ".":
        output += String.fromCodePoint(m[p]);
      break;
      case ",":
        m[p] = iput.codePointAt(input_num) % 256;
        input_num++;
      break;
      case "[":
        indent_m.push(i);
        indent++;
      break;
      case "]":
        if(m[p] !== 0){
          i = indent_m.pop();
        }
        indent--;
      break;
    }
  }
  return output;
}```
これでもおかしくなります
