Web backend development is a job for young people.

Because the entire programmer industry is a job for young people, both front-end and back-end development will face elimination at around 35 years old, and the older you are, the less physical fitness and stress resistance you have in all aspects will be compared to young men in their 20s. The later you get, the less valuable your work ability will be, so it is a job for young people.

I personally think that front-end development is just hard labor, and there is no technical content. . . You should be cautious in your prime years~!
