node-espree 9.4.1~dfsg-2 (amd64 binary) in ubuntu oracular

 Espree started out as a fork of Esprima v1.2.2,
 the last stable published released of Esprima
 before work on ECMAScript 6 began.
 Espree is now built on top of Acorn,
 which has a modular architecture
 that allows extension of core functionality.
 The goal of Espree is to produce output
 that is similar to Esprima with a similar API
 so that it can be used in place of Esprima.
