停止类型记录中的程序执行

Question

练习Javascript，如果我想测试一个代码块

function logic(a, b){
   x= a+b;
   y = x-5;
   console.log(y);
   return; // This is my break statement to make sure the function runs until y.

  z = y*10; //This line is not executed.
}

现在，在使用angular2练习打字本时，如果我使用返回

logic(a, b) => {
       x= a+b;
       y = x-5;
       console.log(y);
       return; // Throws error

      z = y*10; //I need to comment out this line to avoid error
    }

它说无法到达的代码检测到了。我有没有办法阻止死刑。

答案是更新根文件夹中的tsconfig.json

{
    "compileOnSave": false,
    "compilerOptions": {
        "outDir": "./dist/out-tsc",
        "sourceMap": true,
        "declaration": false,
        "moduleResolution": "node",
        "emitDecoratorMetadata": true,
        "experimentalDecorators": true,
        "allowUnreachableCode": true, //add this line
        "lib": [
            "es2016"
        ]
    }
}

Answer 1

是的，设置--allowUnreachableCode。请参阅：https://www.typescriptlang.org/docs/handbook/compiler-options.html
