# 2.0.0 - 13.11.2017 functions can be used for function programming for easealy, as they are shipped independently instead of using * ES6: `import calc from "node-bytes-calculator";` or * commonjs: `const calc = require("node-bytes-calculator")` now * ES6: `import { hasSequence, addSequence, removeSequence } from 'sequence-calculator';` or * commonjs: `const { hasSequence, addSequence, removeSequence } = require('sequence-calculator');` functions renamed * instead of `calc.hasBytes(x, y)` just `hasSequence(x, y)` * instead of `calc.addBytes(x, y)` just `addSequence(x, y)` * instead of `calc.removeBytes(x, y)` just `removeSequence(x, y)` functions are shipped as __arrow functions__ e.g. {this} is not redifined in those [as there is no need for that]
