				test: /\.mathjs?$/,
				loader: 'mathjs-webpack-loader'
			}
		]
	}
};

index.js

import expressions from 'expressions.mathjs';
import mathjs from 'mathjs';

const instance = mathjs.create();
const compiled = expressions(instance).map(exp => exp.compile());

console.log(compiled[0].eval({x: 4, y: 1})); // 20
