[!IMPORTANT] As announced on the OpenJS Foundation blog, Lodash has received support from the Sovereign Tech Agency and will transition to the Feature-Complete maturity stage so that it remains stable, secure, and sustainable long-term. As part of this effort, Lodash is rebooting its governance. A draft charter will be published shortly. The upcoming Technical Steering Committee (TSC) is already at work. For transparency, its members are listed in GOVERNANCE.md.

The Lodash library exported as a UMD module.

Generated using lodash-cli:

$ npm run build
$ lodash -o ./dist/lodash.js
$ lodash core -o ./dist/lodash.core.js

• Manipulating & testing values
• Creating composite functions
