TS的tsconfig.json配置

今天TS群里的小伙伴使用ES2017的 特性padEnd
ES2017 中新的字符串方法：padStart 和 padEnd
发现vscode会报错 虽然不影响编译 但是一条红线还是让人很不舒服
后来群里的大佬发现他的tsconfig.json有问题
参照以下内容可解决问题

{
  "compilerOptions": {
    "baseUrl": ".",
    "outDir": "build",
    "module": "esnext",
    "target": "es5",
    "lib": ["esnext", "dom"],
    "sourceMap": true,
    "allowJs": true,
    "jsx": "react",
    "moduleResolution": "node",
    "rootDir": ".",
    "forceConsistentCasingInFileNames": true,
    "noImplicitReturns": true,
    "noImplicitThis": true,
    "noImplicitAny": true,
    "noUnusedLocals": true,
    "noUnusedParameters": true,
    "strictNullChecks": true,
    "importHelpers": true,
    "suppressImplicitAnyIndexErrors": true,
    "experimentalDecorators": true,
    "downlevelIteration": true,
    "allowSyntheticDefaultImports": true,
    "paths": {
      "@/*": ["src/*"]
    }
  },
  "exclude": ["node_modules", "dist", "build", "mock"]
}
