This is not a complete list. · One-page guide to Lodash Lodash is a javascript library for utility functions. Lodash is very easy to use and simple to integrate into javascript client and server side like nodejs applications. Advantages with this library support latest and older browsers. Developer need not think about how it works in the older browser as it is a stable library Reference 'lodash' correctly is crucial for the performance of your code and in case of package size. You get a good result out of it even you don't use the subset. My assumption in case of the subset is that somewhere an SPFx library component deployed to Office 365 that contains some function of lodash Import Specific Function from Lodash Library. Rather than importing the whole library, which will take more disk space, you can import specific functions that you want to use.

Once downloaded, the package tarball from the NPM registry can be extracted using the tar command: $ tar -xzf lodash-4.17.4.tgz. The tar command will extract the contents of the package tarball downloaded from the NPM registry. The name of the extracted folder is package/ - this is likely because it's the default behavior of npm pack when npm. The lodash-es library supports tree-shaking out of the box because it uses ES modules. However, with lodash v4, tree-shaking works without additional configuration in Webpack v4. It is also worth noting is that if you use lodash-es and you have other dependencies that require lodash, both will end up in the app bundle Lodash provides tons of utility methods, making your code more fast and elegant. However, those tons of useful methods come with a cost - Lodash weights more than 70 KB of minified code. This is a significant addition even for the heavy apps. Moreover, chances are you are using just a handful of methods from the whole library
