Version Details and Security Vulnerabilities

Moment.js version 2.13.0 arrived on April 18, 2016, succeeding version 2.12.0, released on March 7, 2016. Both versions maintain the core function of parsing, validating, manipulating, and displaying dates in JavaScript. Examining the devDependencies reveals subtle changes, likely reflecting updates in the tooling used for development and testing. Both versions share an extensive suite of development dependencies, including testing frameworks like Karma and QUnit, build tools like Grunt, and utilities for code quality and coverage such as JSHint, JSC, and Coveralls. The presence of tools like esperanto suggests ongoing efforts to modernize the codebase and support ES6 modules and the toolchain to test on different browsers such as Chrome and Firefox and also different platforms with Sauce Labs.
