Differentiate between "\n" and endl

[Fabulouskenn]

what is the major difference between ("\n") and (endl)when used in c++

[JLBorges]

std::endl

Inserts a newline character into the output sequence (os) and flushes it...
...
In most (other) usual interactive I/O scenarios, std::endl is redundant when used with std::cout because any input from std::cin, output to std::cerr, or program termination forces a call to std::cout.flush(). Use of std::endl in place of '\n', encouraged by some sources, may significantly degrade output performance.
...
The code samples on this wiki follow Bjarne Stroustrup and The C++ Core Guidelines in flushing the standard output only where necessary.

Perhaps some documentation for endl might clear up the differences?
