How are you using Babel?

Programmatic API (babel.transform, babel.parse)

Input code

const test = (data) => {
  for (let i = 0; i < data.length; i++) {
    const x = data[i];
    data.find((item) => item === x);
  }
  for (let i = 0; i < data.length; i++) {
    const x = data[i];
    data.find((item) => item === x);
  }
}

Configuration file name

.babelrc

Configuration

{
"presets": [
"@babel/preset-env"
]
}

Current and expected behavior

current output:

"use strict";

var test = function test(data) {
  var _loop = function _loop() {
    var x = data[i];
    data.find(function (item) {
      return item === x;
    });
  };
  for (var i = 0; i < data.length; i++) {
    _loop();
  }
  var _loop2 = function _loop2() {
    var x = data[i];
    data.find(function (item) {
      return item === x;
    });
  };
  for (var _i = 0; _i < data.length; _i++) {
    _loop2();
  }
};

the second var x = data[i]; should be var x = data[_i];
