Answer 1

Well as far as braces go, if I am correct there are 3 different ones: () , [] and {}. The() ones are usually used in functions or if statements etc.and you place variables or Boolean vues inside them(not the best explanation).The [] ones are usually used for declaring arrays and the {} ones are usually used as the begging and the end of a code block in a function(you put instructions between them).Idk if this is a fine explanation but I hope you get the basic idea! :-)
