The Babel development team reported on the release of the seventh version of the transpair - a tool that rewrites code from one language to another at a comparable level of abstraction or from one version of the AP to another. The release of Babel 7 required 2 years of labor, 4 thousand commits and 50 pre-releases.

As a result, it denied Node.js versions 0.10, 0.12, 4, 5, received a new tool babel-upgrade to automatically install updates, as well as support for TypeScript.

Babel 7 Features

  • The rejection of unsupported versions of Node.js is 0.10, 0.12, 4 and 5.
  • @babel namespace migration. For example, the babel-core is now represented as @ babel / core.
  • Refusal to publish preset-es2015 annual presets and complete transition to the only one: babel-preset-env. It compiles the code with the latest JavaScript release and replaces the old presets.
  • Renaming some packages: all the plug-ins suggested by the TC39 committee will be marked -proposal, not-transform.
  • Adding a tool for automatically updates install - babel-upgrade.
  • Adding a new configuration file is babel.config.js.
  • Support for plug-ins and presets.
  • Support for TypeScript in the @ babel / preset-typescript preset

Babel is a tool that allows JavaScript developers to use the current language syntax, not paying attention to backward compatibility issues with older versions in browsers.
