Description

Instead of assigning the innerText and onClick properties to specific strings and functions like it does now, the update function will use data from the location that is passed into it. First, data needs to be passed into the update function. Inside the goTown function, call the update function.

Here is how you would call a function named exampleFunction: exampleFunction();

Instructions

Tests

tests:
  - text: See description above for instructions.
    testString: assert(goTown.toString().match(/update\(\)/));
