Bug Report

• TSLint version: 5.4.3
• TypeScript version: 2.3.4
• Running TSLint via: CLI

TypeScript code being linted

// code snippet
const obj = {};
obj["__id__"] = "foobar";
// then execute: tslint -c tslint.json 'src/**/*.ts' --fix

with tslint.json configuration:

{
  "extends": "tslint:recommended",
  "rules": {
    "interface-name": false,
    "new-parens": true,
    "no-arg": true,
    "no-bitwise": true,
    "no-conditional-assignment": true,
    "no-shadowed-variable": false,
    "no-console": true,
    "object-literal-sort-keys": false,
    "max-line-length": [
      true
    ]
  },
  "jsRules": {
    "max-line-length": [
      true
    ]
  }
}

Actual behavior

const obj = {};
obj.___id__ = "foobar";  //  three '_' 囧rz

Expected behavior

const obj = {};
obj.__id__ = "foobar";

There seems to be a bug in typescript's AST. I opened microsoft/TypeScript#16788 to track this.

Even though that bug is fixed with typescript@2.5.0, I added a fix for older version of typescript: #3184
