You know, a list of reserved words, what their functions are, how the structure works, etc ... the kind you'll see if you pick up some "intro to <language X>" book from no-starch or o'reilly or the kind that GNU Awk/sed/dc have.
If anything, it’s _too_ formal and may be missing some example for more complex usages that combine several features.
Python (dead simple, easy to recall):
if monkey == 'fat':
print('happy')
if [ "$monkey" = 'fat' ]; then
echo 'happy'
you gonna forget about the semicolon, the spaces around the condition and it will error out. not to mention integer comparison operators...
python also has some terrible syntax, but those are advanced things, like list comprehensions.
jq...it's the same as awk, sed, bash... hard to remember for the reasons mentioned above
