# Proposed language features
#
# This project accepts tests for language proposals that have reached stage 3
# in TC39's standardization process. Those tests should be annotated with a
# dedicated feature flag so that consumers may more easily omit them as
# necessary.

# Standard language features
#
# Language features that have been included in a published version of the
# ECMA-262 specification. These flags are largely maintained for historical
# reasons, though their use for relatively new features (i.e. prior to
# availability across major implementations) is appreciated.
