           "content": "Just like `{...}` brackets, functions can be nested. You can create functions within functions, or brackets within functions, or vice versus. All of these create new unique scopes. And they can be very nested\\! For instance, consider the following code:\n\n```typescript\nconst aVeryScopedWorld = () => {\n  // The main function scope\n\n  {\n    // Some brackets scope\n    const anotherFunction = () => {\n      // Now we are inside a new function and new scope\n      for (let i = 0; i < 10; i++) {\n        // A new scope, yet again!\n\n        const theForLoopFunction = () => {\n          // A function defined inside the for loop!\n          // Yes, it also creates a new scope!\n          return i;\n        }\n\n        const result = theForLoopFunction();\n        console.log(result);\n      }\n    }\n  }\n}\n\n```\n\nOk, this is a bit overkill\\! But it should get the idea across. Each of these new functions or brackets creates a new local scope\\!\n\nAlso, it's worth pointing out how flexible TypeScript is here. You can create and nest different constructs like this in very flexible ways. This gives you a lot of options as you craft programs to perform tasks and also as you think about the design, organization, and architecture of your programs.\n\nFor instance, should you create that new function right here, in the body of another function, or should you write outside in order to better separate your code?"

This helps to improve the organization and readability of your program, and it may prevent bugs and problems as well.\n\nHowever, scope is not the only tool a programmer has to accomplish a goal like this.\n\nLater on, you will learn how to write programs and build apps using a real code environment \\(not this fun editor playground in a browser\\!\\). When you reach that stage, you will have a lot of other tools at your disposal.\n\nFor example, you can define parts of your program in different files, put related files in different folders, and then _import_ values from one file into another. You can also control what you _import_ and _export_. This is a very powerful capability for organizing software programs. These same skills will also allow you to download open source code other people have written and import this code in your own projects as well\\! This is incredibly useful and opens the doors to building a number of interesting applications\\!\n\nYou will learn the details of this later, but for now just keep it in mind as a short preview and extension of the ideas of scopes which will come in handy later\\!\n\nTake a look at this code snippet for a short teaser:\n\n```typescript\n// This imports the library \"request\", which is open source and written\n// and maintained by other developers.\nimport request from \"request\";\n\n// The request library lets you make HTTP requests to URLs!\nrequest(\"http://www.google.com\", (error, response, body) => {\n  if (error) {\n    throw error;\n  } else {\n    console.log(\"Success!, Response received: \", body);\n    // Do somethine else here...\n  }\n});\n\n```\n"
