Async/await examples in docs don’t run

[Ivo-Balbaert]

Describe the bug All examples in async/await have either runtime or compilation issues:

Example 1: Windows 10:  error:  (node:8404) UnhandledPromiseRejectionWarning: ReferenceError: fetch is not defined      at D:\Clio\own_projects\await1\build\main.clio.js:1:187 -- at run (D:\Clio\own_projects\await\build\node\node_modules\clio-run\src\index.js:106:26) -- at async D:\Clio\own_projects\await\build\node\node_modules\clio-run\src\runners\wt.js:32:5 -- (Use node --trace-warnings ... to show where the warning was created) -- (node:1056) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by -- throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag --unhandled-rejections=strict (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 2) -- (node:1056) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code. -- <-- This process hangs

-- Output should be: -- {"organization_name":"Telenet BVBA","region":"Flanders","accuracy":5,"asn":6848,"organization":"AS6848 Telenet BVBA","timezone":"Europe\/Brussels","longitude":"4.4487","country_code3":"BEL","area_code":"0","ip":"81.83.67.231","city":"Mortsel","country":"Belgium","continent_code":"EU","country_code":"BE","latitude":"51.1662"}

in Playground:

[TypeError: Failed to fetch] ← probably same error

Example 2: await outside of flow

Windows 10 / Playground:  same error

Example 3: await block:

Windows 10:

  await:
    ^

Expecting one of lineBreak, conditional, fullConditional, function, symbol, parameter, number, array, string, formattedString, hashmap, propertyAccess, range, rangeFull, rangeBy, byRange, ranger, slice, set, wrapped, awaited, parallelFn, null, true, false, inCheck, group, assignment, arrowAssignment, math, comparison, logical, logicalNot, call, imported, outdent but encountered colon

Playground:   same error

Example 4: await [] same error as Example 3 Example 5: await keyword: same error as Example 3

To Reproduce Steps to reproduce the behavior:

1. Run code samples on page
2. See error

Expected behavior json outputs of the fetch commands

Screenshots If applicable, add screenshots to help explain your problem.

Versions (please complete the following information):

• OS: Windows 10 + Playground
• Clio: 0.8.1
• Node: v14.16.1
• NPM: 6.14.12

Possible solutions

If fix is not evident, either remove the section (temporarily) or write a header: WIP: In the current version 0.8.1 these code examples don't work

Additional context It was mention on Telegram that it would be fixed in v0.8, but it isn't

This issue is fixed, for some reason Gitbook was building the old documentation source files.

After installing Clio 0.8.2 , creating a new project and copying the code from the async/await example in a project, I still get the same error in Windows 10:

All async/await programs: On Playground give the error: [TypeError: Failed to fetch]

(node:10332) UnhandledPromiseRejectionWarning: ReferenceError: fetch is not defined

I forgot the fact that fetch is browser only and the example does not run in node without first installing and importing node-fetch. I'll update the documentation, maybe come up with another async / await example.
