停止程序的執行打字稿

Question

使用Javascript練習，如果我想測試的代碼塊現在

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. 
} 

而與angular2打字稿練習，如果我用回

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 
    } 

它說檢測不到的代碼。有什麼辦法可以阻止執行嗎？

答案是在根文件夾

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

更新tsconfig.json是，設置--allowUnreachableCode。參見：https://www.typescriptlang.org/docs/handbook/compiler-options.html
