## 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.
