NodeJS - urlObject.slashes Property

---

---

The NodeJS urlObject.slashes property of urlObject retrieves a Boolean value. The returned value will be true, if two ASCII forward slashes (//) are required after the colon (:) in the protocol segment of the URL. Else, the returned value is false.

The URL (Uniform Resource Locator) is a unique web address for a specific resource present in the various web servers.

The protocols present in the URL specify how data is transferred between the host and a web browser. The most common protocols you find the URLs are HTTP and HTTPS (secure), but there are other internet protocols such as FTP, UDP, POP, SMTP, DNS, etc.

console.log(url.parse('DHCP://site.com').slashes);
console.log(url.parse('IMAP4://site.com').slashes);
console.log(url.parse('SIP://site.com').slashes);
console.log(url.parse('RTP://site.com').slashes);
console.log(url.parse('RLP://site.com').slashes);
console.log(url.parse('RAP://site.com').slashes);
console.log(url.parse('L2TP://site.com').slashes);
console.log(url.parse('PPTP://site.com').slashes);
console.log(url.parse('SNMP://site.com').slashes);
console.log(url.parse('TFTP://site.com').slashes);

console.log(url.parse('UDP://site.com').slashes);
console.log(url.parse('POP://site.com').slashes);
console.log(url.parse('SMTP://site.com').slashes);
console.log(url.parse('FTP://site.com').slashes);
console.log(url.parse('HTTP://site.com').slashes);
console.log(url.parse('HTTPS://site.com').slashes);

Output
