-- Lingo syntax
put(not (1 < 2))
// JavaScript syntax
put(!(1 < 2));
Because 1 is less than 2, the result is 0, which indicates that the expression is
FALSE
.
This statement determines whether 1 is not greater than 2:
-- Lingo syntax
put(not (1 > 2))
// JavaScript syntax
put(!(1 > 2));
Because 1 is not greater than 2, the result is 1, which indicates that the expression is
TRUE
.

the checkMark
menu item property for Bold in the Style menu to the opposite
of its current setting:

menu("Style").menuItem("Bold").checkMark = \

end resetMenuItem
// JavaScript syntax
function resetMenuItem() {
menu("Style").menuItem("Bold").checkMark =
!(menu("Style").menuItem("Bold").checkMark)
}
