Primary expressions are the simplest expressions. There are three groups of primary expressions: literal values, variable references, and some keywords.
The logical OR ( || ) operator (logical disjunction) for a set of operands is true if and only if one or more of its operands is true. It is typically used with Boolean (logical) values. When it is, it returns a Boolean value.

-1 means the first goes before the second, 1 means it goes after, and 0 means they’re equivalent. The sort function uses the comparisons in the function you pass it to sort the function.
What are the operators?
1. In mathematics and sometimes in computer programming, an operator is a character that represents an action, as for example x is an arithmetic operator that represents multiplication. In computer programs, one of the most familiar sets of operators, the Boolean operators, is used to work with true/false values.
