Tests

tests:
  - text: ''
    testString: 'assert(typeof reusableFunction === "function", "<code>reusableFunction</code> should be a function");'
  - text: ''
    testString: 'assert("Hi World" === logOutput, "<code>reusableFunction</code> should output "Hi World" to the dev console");'
  - text: ''
    testString: 'assert(/^\s*reusableFunction\(\)\s*;/m.test(code), "Call <code>reusableFunction</code> after you define it");'

Challenge Seed

// Example
function ourReusableFunction() {
  console.log("Heyya, World");
}

ourReusableFunction();

// Only change code below this line

Before Test

var logOutput = "";
var originalConsole = console
function capture() {
    var nativeLog = console.log;
    console.log = function (message) {
        if(message && message.trim) logOutput = message.trim();
        if(nativeLog.apply) {
          nativeLog.apply(originalConsole, arguments);
        } else {
          var nativeMsg = Array.prototype.slice.apply(arguments).join(' ');
          nativeLog(nativeMsg);
        }
    };
}

function uncapture() {
  console.log = originalConsole.log;
}

capture();

After Test

console.info('after the test');
