EVERY LANGUAGE TRADES OFF SPEED OF WRITING, SPEED OF RUNNING, SAFETY AND CONTROL
None achieves all four. Most language arguments are about which trade-offs matter for a particular problem.
CONCEPTS TRANSFER; SYNTAX DOES NOT
Variables, control flow, functions, data structures and error handling are the same everywhere, which is why the second language is far easier than the first.
Learn the differences first — typing, memory, concurrency and error handling shape everything else.
THE ECOSYSTEM MATTERS MORE THAN THE SYNTAX
You will spend more time using libraries than admiring language features, and several domains decide the language for you.
MEMORY FAULTS AND RACE CONDITIONS ARE THE HARDEST CLASSES OF BUG
Which is why languages eliminating them at compile time have gained ground, and why memory-safe languages are preferred in security-sensitive work.
MOST APPLICATIONS ARE NOT LIMITED BY THEIR LANGUAGE
Measure before concluding otherwise. It is nearly always a query without an index or a request in a loop.
NEVER SILENTLY DISCARD AN ERROR, IN ANY LANGUAGE
The program continues in an unknown state with the cause invisible.
ADOPT THE LANGUAGE'S FORMATTER, LINTER AND TESTING TOOLS IMMEDIATELY
And write idiomatically — code following conventions is read faster and maintained by anyone who knows the language.
