JavaScript: Link processing

url.js

Implement an abstraction for working with URLs. It should extract and change URL parts. Its interface:

• make(url), a constructor that creates a URL
• setProtocol(data, protocol), setter that sets a communication protocol
• getProtocol(data), getter (selector) that returns a communication protocol
• setHost(data, host), setter that sets a host
• getHost(data), getter that returns a host
• setPath(data, path), setter that sets a URL path
• getPath(data), getter that returns a URL path
• setQueryParam(data, key, value), setter that sets query parameters
• getQueryParam(data, paramName, default = null), getter that returns query parameters. The third parameter of the function is the default value, which is returned when no such parameter found in the query
• toString(data), getter that transforms URL to string

const url = make('https://hexlet.io/community?q=low');

setProtocol(url, 'http:');
toString(url); // 'http://hexlet.io/community?q=low'

setPath(url, '/404');
toString(url); // 'http://hexlet.io/404?q=low'

setQueryParam(url, 'page', 5);
toString(url); // 'http://hexlet.io/404?q=low&page=5'

setQueryParam(url, 'q', 'high');
toString(url); // 'http://hexlet.io/404?q=high&page=5'

Tips

• Use the standard URL: URL
• set() and 'get()' methods
