Which software language is good for web developer

Hi Folks,

Greetings of the day!

I am your pal, wanting to clarify certainly pops up into my mind about web development.

Start with - HTML5+CSS+ ? which language is best which will have future longevity run like another 20 years without doubts would run. However, having questions on react, node.js.angular, JSquery etc. Please clarify.

Very less pattern provided in lesson wise in LearnVern HTML…any comments on this.
