Difference between || and ?? operators - Stack Overflow
...The main difference between ?? and || is how they handle falsy values. ?? only considers null and undefined as nullish, while || considers any falsy value as potentially false. In summary, use the nullish coalescing operator ?? when you specifically want to handle null or undefined and use the logical OR operator || when you want to handle any falsy value (including null and undefined)....

bitwise operators - What does the 'and' instruction do to the operands ...
...This should be described in the documentation for any assembler that has an and instruction. It does a bit-wise Boolean "and" between two operands. In other words, corresponding bits (bit n in each operand) are anded, in the Boolean operation sense, giving bit n of the result. In Boolean logic, 1 and 1 = 1, but 0 and x (anything else) = 0. Thus, 10111010 and 01101011 results in 00101010. If ......

What is Python's equivalent of && (logical-and) in an if-statement?
...There is no bitwise negation in Python (just the bitwise inverse operator ~ - but that is not equivalent to not). See also 6.6. Unary arithmetic and bitwise/binary operations and 6.7. Binary arithmetic operations. The logical operators (like in many other languages) have the advantage that these are short-circuited. That means if the first operand already defines the result, then the second ......

An "and" operator for an "if" statement in Bash - Stack Overflow
...In each of these, ] is the final argument to the invocation of [, as required. The shell parses && and ; as tokens which terminate the [ command, but strings like -a, [[, and ]] are just strings that the shell passes to the command. (In the first case, the shell treats 2> /dev/null as a redirection operator, so those strings are not passed to [ as arguments). Note that using -a as an argument ......

java - && (AND) and || (OR) in IF statements - Stack Overflow
...Java has 5 different boolean compare operators: &, &&, |, ||, ^ & and && are "and" operators, | and || "or" operators, ^ is "xor" The single ones will check every parameter, regardless of the values, before checking the values of the parameters. The double ones will first check the left parameter and its value and if true (||) or false (&&) leave the second one untouched. Sound compilcated? An ......
