var loc = "foo";
console.log (loc);
}
mi prueba(); // logs "foo"
console.log (loc); // loc no esta definido
loc no está definido fuera de la función. Instructions
myVar dentro de myLocalScope . Ejecute las pruebas y luego siga las instrucciones comentadas en el editor. Insinuación Actualizar la página puede ayudar si te quedas atascado.
Tests
tests:
  - text: Ninguna variable global <code>myVar</code>
    testString: 'assert(typeof myVar === "undefined", "No global <code>myVar</code> variable");'
  - text: Agrega una variable <code>myVar</code> local
    testString: 'assert(/var\s+myVar/.test(code), "Add a local <code>myVar</code> variable");'
Challenge Seed
function myLocalScope() {
  'use strict'; // you shouldn't need to edit this line
  console.log(myVar);
}
myLocalScope();
// Run and check the console
// myVar is not defined outside of myLocalScope
console.log(myVar);
// Now remove the console log line to pass the test
Before Test
var logOutput = "";
var originalConsole = console
function capture() {
  var nativeLog = console.log;
  console.log = function (message) {
    logOutput = message;
    if(nativeLog.apply) {
      nativeLog.apply(originalConsole, arguments);
    } else {
      var nativeMsg = Array.prototype.slice.apply(arguments).join(' ');
      nativeLog(nativeMsg);
    }
  };
}
function uncapture() {
  console.log = originalConsole.log;
}
After Test
console.info('after the test');
