Installation

• I'm using Node.js, Webpack, Browserify, Rollup, or another module bundler, and install packages from npm.
  • First, install the simple-statistics module, using npm install simple-statistics, then include the code with require or import:
  • I use the require function to use modules in my project. (most likely)
    • When you use require, you have the freedom to assign the module to any variable name you want, but you need to specify the module's name exactly: in this case, 'simple-statistics'. The require method returns an object with all of the module's methods attached to it.
      

      var ss = require('simple-statistics')

  • I use import to use modules in my project. I'm probably using Babel, Webpack, or Rollup.
    • This module only supports the 'default' export when you're using ES6 module: so you can import all of its methods, attached to an object, like in this example. Importing specific methods will work in Babel, but not in Rollup.
      

      import ss from 'simple-statistics';

• I'm not using a module bundler. I'm writing a web page, and want to include simple-statistics using a script tag.
  • When you use simple-statistics from a script tag, you don't get to choose the variable name it is assigned to: simple-statistics will always become available globally as the variable ss. You can reassign this variable to another name if you want to, but doing so is optional.

    <script src='https://unpkg.com/simple-statistics@5.0.0/dist/simple-statistics.js' />

    There are two options for the src attribute of that script tag: one with .min.js that is compressed, and the other without, that is raw.
