这个概念是对于逻辑运算符&&和||而言的,是一种逻辑运算符的求值策略。只有当第一个运算数的值无法确定逻辑运算的结果时,才对第二个运算数进行求值。例如,当&&的第一个运算数的值为false时,其…
does not perform short-circuit evaluation "Does not perform short-circuit evaluation" 通常指的是某个表达式或语句不会利用短路求值(short-circuit evaluation)的特性。在编程中,短路求值是一种优化技术,它允许程序员在逻辑表达式中提前终止某些条件的计算。这通常是通过使用逻辑运算符(如&&或||)来完成的。 例如,...
这种方式被称为“不执行短路求值”(does not perform short-circuit evaluation)。 在一些编程语言中,当使用逻辑运算符“&&”进行逻辑与操作时,如果第一个表达式的结果为假,那么第二个表达式将不会被执行。这种情况下就是短路求值的应用。但在不执行短路求值的情况下,无论第一个表达式的结果是什么,第二个表达式...
“短路求值(Short-Circuit Evaluation) // 逻辑与和逻辑或操作符总是先计算其做操作数,只有在仅靠左操作数的值无法确定该逻辑表达式的结果时,才会求解其右操作数。 functionaa() {if(null) { console.log('null') }if(undefined) { console.log('undefined') }if(false) { console.log('false') }if(tr...
Short-circuit evaluation, minimal evaluation, or McCarthy evaluation denotes the semantics of some Boolean operators in some programming languages in which the second argument is only executed or evaluated if the first argument does not suffice to determine the value of the expression: when the ...

2. Understanding Short-Circuit Evaluation JavaScript’s&&(AND) operator, while seemingly straightforward, introduces a hidden efficiency mechanism known as short-circuit evaluation. This behavior can lead to surprising results if you’re not familiar with it. Let’s delve into how short-circuit evalua...
