Lowercase the keys of an object

An Object.keys replacement, in case Object.keys is not available. From https://github.com/es-shims/es5-shim

Sort the keys of an object

Iterate over the own and inherited enumerable properties of an object, and return an object with properties that evaluate to true from the callback. Exit early by returning `false`. JavaScript/Node.js

Create nested values and any intermediaries using dot notation (`'a.b.c'`) paths.

Map object keys and values into a new object

Deeply mix the properties of objects into the first object. Like merge-deep, but doesn't clone. No dependencies.

Convert object keys to camel case

ES2017 spec-compliant Object.values shim.

Invert the key/value of an object. Example: `{foo: 'bar'}` → `{bar: 'foo'}`

ES2017 spec-compliant Object.entries shim.

Iterate over the own enumerable properties of an object, and return an object with properties that evaluate to true from the callback. Exit early by returning `false`. JavaScript/Node.js.

ES proposal-spec-compliant Object.fromEntries shim.

Convert object keys from camel case

The lodash method `_.keys` exported as a module.

Recursively merge values in a javascript object.
