babel-traverse 6.7.4

v6.7.4

on Node.js NPM

Bug Fix

• babel-traverse

  • #3419: Keep the context stack balanced to ensure that contexts are properly popped off. (@loganfsmyth)

    This bug was causing issues internally because the context system relies on the queues being balanced when deciding what nodes need to be re-processed and which do not. When it becomes imbalanced, nodes can be forgotten or skipped, causing issues like https://phabricator.babeljs.io/T7199 which broke ES6 modules on IE8 with the ES3 transforms.

  • #3420: Invalidate the scope cache when nodes are moved. (@loganfsmyth)

    This bug was causing scoping issues in some cases if a node was moved to a new location that was not nested inside a new scope. When this case was hit, the old cached scope would be used, causing issues like https://phabricator.babeljs.io/T7194, https://phabricator.babeljs.io/T6934, and https://phabricator.babeljs.io/T6728.
