Day 20 of JavaScriptmas - Domain Type Solution

Day 20 challenge is to return an array of information from the domain name based on the last dot (.)

For example, an array of ["en.wiki.org", "codefights.com", "happy.net", "code.info"] will return ["organization", "commercial", "network", "information"]

I also mapping each domain name .com for commercial, .info for information, .net for network, .org for organization.

These are two methods that I found to solve the challenge

1st - Mapping domain with filter

function domainType(domains) {
    let typeNames = [
        {id: 'com', desc: 'commercial'},
        {id: 'info', desc: 'information'},
        {id: 'net', desc: 'network'},
        {id: 'org', desc: 'organization'}
    ];

    const result = domains.map( url => {
        const urlType = url.split('.').pop();       

        let name = typeNames.filter(name => {
           if(urlType === name.id) {
                return name;
           } 
        });
        name = Object.assign({}, ...name);

        return name.desc;
    });

    return result;
}

2nd - Mapping domain with switch

function domainType(domains) {
    let result = domains.map(domain => {
        switch(domain.split('.').pop()) {
            case 'com':
                return 'commercial';
                break;
            case 'info':
                return 'information';
                break;
            case 'net':
                return 'network';
                break;
            case 'org':
                return 'organization';
                break;
            default: 
             return 'unknown domain';
        }
    });
    return result;
}

Both methods are good for memory muscles, but I found out that the first one most likely going to be the common case.
