They sometimes apply to different types, e.g. len, cap, and append, or they have to operate near system level like panic. That’s why they need support from the compiler.

Explanation

Some of the functions are covered before in detail and used multiple times, so we won’t run them from scratch. Functions that were not discussed previously, their running examples will be provided later in the course in detail, section by section. So don’t ...
