How does Jingdong realize that multiple attributes of a product correspond to multiple pages?

How does JD implement multiple attributes corresponding to multiple pages for one product? What is the difference between it and Taobao’s technology?
For example, search on JD.com for [Meizu Meizu Blue E 32GB Full Netcom Public Edition Champagne Gold Mobile Unicom Telecom 4G Mobile Phone Dual SIM Dual Standby]
On the product details page,
select the color of "Champagne Gold" and the URL in the address bar Display https://item.jd.com/3475396.html
If you select another color "Moonlight Silver", it will jump to the https://item.jd.com/3475418.html address page
Same , the same color, different versions, the same is true, for example, the color is "Moonlight Silver", the versions are as follows
All Netcom public version https://item.jd.com/3475418.html
All Netcom mobile version https:/ /item.jd.com/3187221.html
Full Netcom Telecom version https://item.jd.com/3629066.html

Excuse me, how is this achieved, and what are the differences from Taobao’s technology?
What are the advantages and disadvantages of this?
Please give me some advice....
