for-await was transformed in @babel/helper-remap-async-to-generator, which was
called by @babel/plugin-transform-async-to-generator and
@babel/plugin-proposal-async-generator-functions. This prevented for-await
statements in async functions to be transpiled if the
transform-async-to-generator plugin was't enabled.
* Avoid adding #__PURE__ annotation to .bind(this)() expressions
Fixes the #__PURE__ annotation getting added to (async () => {})() IIFEs when the arrow function transform is running with spec: true.
* Return false instead of undefined
* Fix indentation in json files
* Add one more case to the async-iife fixtures
This commit introduces 4 changes:
1) Function declarations are wrapped using function declarations.
This has two advantages:
- We can rely on native hoisting, instead of using _blockHoist
- The function isn't wrapped until it is called. This avoids
problems where `regeneratorRuntime.wrap` was called before
that `babel-polyfill` was imported.
Example:
function fn() {}
// becomes
function fn() { return _fn.apply(this, arguments); }
function _fn() {
_fn = _wrapper(/* Original function ... */);
return _fn.apply(this, arguments);
}
2) Use a single template for both named and anonymous function
expressions. They already had the same behavior, but the one
used for named functions was a bit longer.
3) Use normal functions instead of arrow functions to wrap
function expressions.
4) Generate a name based on the original one for wrapped
functions (e.g. `foo` becomes `_foo` instead of `_ref`).
* for-of: IteratorClose spec compatibility.
See #3:
https://tc39.github.io/ecma262/#sec-iteratorclose
* Update spec fixtures for for-of.
* Fix IteratorClose case for remap-async-to-generator.
* Fix IteratorClose case for async-generator-function test output.
* Modify few tests according to iteratorClose fix.
* Fix iteratorClose for helpers.slicedToArray also.
* Update iteratorClose fixture for commonjs.
* Create "babel-helper-wrap-function"
It contains the logic to wrap a function inside a call expression.
It was part of the "babel-helper-remap-async-to-generator" package, but
it is needed to transpile "function.sent"
* Create "babel-transform-function-sent"
It transforms the "function.sent" meta property by replacing it with
"yield" and making the generator ignore the first ".next()" call.
* "function.sent" is the last value passed to .next(), not the first one
* Disable exec tests on old node
* Fix flow error
* Add "transform-function-sent" to "stage-2" preset
* Do every trasformation in one traversal
* Test for "yield function.sent"
* [skip ci]
* Fix some typos [skip ci]
* Handle arrow function processing via shared API rather than default plugin.
* Fix a few small PR comments.
* Preserve existing spec arrow 'this' rewrites, and support spec in subclass constructors.
