这部分代码使用条件语句if判断a是否小于等于b,如果成立,则执行代码块中的语句,并打印 “a is less than or equal to b”。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 return0;} 最后,这行代码表示程序正常结束,并将零作为返回值传递给操作系统。 逻辑操作符(Logical Operators) ‘

operands that specifies computation of a value, or that designates an object or a function, or that generates side effects, or that performs a combination thereof. The value computations of the operands of an operator are sequenced before the value computation of the result of the operator. ...
The (||) operator (logical OR operator) is use to perform a logical disjunction on two expressions.Syntaxresult = expression1 || expression2 The || operator syntax has these parts: Part Description result Any variable. expression1 Any expression. expression2 Any expression. ...
||The logical-OR operator performs an inclusive-OR operation on its operands. The result is 0 if both operands have 0 values. If either operand has a nonzero value, the result is 1. If the first operand of a logical-OR operation has a nonzero value, the second operand isn't evaluated...
