Additionally, please see previous discussions on this topic: > [@Async property accessor: -\>](https://es.discourse.group/t/async-property-accessor/765): > > The idea is to access a property of an awaited value to allow deep chaining of async operations. Right now, to accomplish that kind of chaining you need to write: const baz = await (await (await fetchFoo()).fetchBar()).fetchBaz(); That can get pretty awkward pretty fast. My idea is a new operator that accomplishes this without all the nested parens: const baz = await fetchFoo()-\>fetchBar()-\>fetchBaz(); Additionally, they can be optionally chained like the other property accessors: const ba… > [@bang await chaining operator](https://es.discourse.group/t/bang-await-chaining-operator/940): > > // this is verbose const response = await fetch('/posts') const posts = await response.json() // chaining multiple await expressions in one line is awkward const posts = await (await fetch('/posts')).json() // proposal: chain together multiple awaits with !. const posts = await fetch('/posts')!.json() > [@The "future-seeing-arrow" proposal.](https://es.discourse.group/t/the-future-seeing-arrow-proposal/1626): > > The idea is to provide a new -\> "operator", that conceptually serves a similar purpose as a "." in a fluent-API, however, it's given a special super-power.

In reality, the -\> syntax is just a simple syntax sugar that decomposes into an array of tuples.
