is-extendable 1.0.1

The is-extendable npm package is a handy utility in JavaScript programming which checks and returns a "True" value if the input is a plain object, an array, or a function. This allows programmers to easily determine if a value can be extended, aiding in functions such as adding properties or methods to the original value.

Utilizing the is-extendable package is an easy process. First, the package must be installed onto your system. This can be done using Node Package Manager (npm) with the command npm install --save is-extendable. Once installed, the module can be required at the top of any JavaScript file using the command var isExtendable = require('is-extendable');. This command imports the functionality of the is-extendable module into the file and assigns it to the variable isExtendable. With this variable, you can check whether a value is extendable by calling isExtendable(value), replacing "value" with the object, array or function you wish to examine.

The is-extendable documentation is scattered throughout various parts of its readme file in its GitHub repository (https://github.com/jonschlinkert/is-extendable). The readme file gives a fundamental overview of the package's capabilities, usage examples, installation instructions, and additional notes about the specifics of its functionality. The readme content is generated by the verb project, and any changes to the documentation must be done through the associated .verb.md readme template.
