@chickendinosaur/object-get-property

Retrieves the property value from an object or nested objects.

Usage no npm install needed!

<script type="module">
  import chickendinosaurObjectGetProperty from 'https://cdn.skypack.dev/@chickendinosaur/object-get-property';
</script>

README

Made in response to the amount that I was using lodash.get to update data in a project and needed a better solution. Ability to cache all key chains to avoid garbage and maintain performance. Backwards compatible with lodash.get.

Passing false as the 3rd param will force no cache.

        },
        {
            three: true
        },
        {
