Disallows awaiting a value that is not a Thenable (await-thenable)

This rule disallows awaiting a value that is not a "Thenable" (an object which has then method, such as a Promise). While it is valid JavaScript to await a non-Promise-like value (it will resolve immediately), this pattern is often a programmer error, such as forgetting to add parenthesis to call a function that returns a Promise.

Rule Details

Examples of code for this rule:

await 'value';

const createValue = () => 'value';
await createValue();

When Not To Use It

If you want to allow code to await non-Promise values. This is generally not preferred, but can sometimes be useful for visual consistency.
