In programming, this quote from W3 schools explains alot and this is this.
A lot of developers chase:
frameworks,
libraries,
stacks,
AI tools,
trendy architectures.
But when things break, the real separator is fundamentals.
A developer who only knows React may struggle when:
state behaves unexpectedly,
async code races,
memory leaks appear,
APIs fail,
performance drops.
Because frameworks abstract complexity, they do not remove it.
Under pressure, you fall back to:
algorithms,
data structures,
networking,
operating systems,
HTTP,
databases,
debugging,
language fundamentals,
computational thinking.
Thatās why someone strong in fundamentals can learn almost any framework quickly, but someone dependent on frameworks often struggles outside their ecosystem.
For example: If you understand HTTP deeply, you can work with REST in almost any stack.
If you understand the DOM and JavaScript properly, learning Vue.js or Angular becomes easier.
If you understand TCP/IP and sockets, tools like Netcat, WebSockets, or backend systems stop feeling āmagical.ā
A senior engineer is usually not the person who memorized the most frameworks.
Itās the person whose fundamentals are so solid that they can reason through unfamiliar problems.
Thatās why many elite programmers repeatedly emphasize:
Learn computer science basics.
Build things.
Debug deeply.
Read low level explanations.
Donāt hide behind abstractions too early.
Frameworks change every few years.
Fundamentals survive decades.
