The conditional operator is also known as the ternary operator. The JavaScript conditional (ternary) operator is only operator that takes three operands a condition followed by a question mark (?), then the first expression to be executed if the condition is truthy followed by a colon (:), ...
The ternary operator evaluates the test condition. If the condition istrue,expression1is executed. If the condition isfalse,expression2is executed. The ternary operator takesthreeoperands, hence, the name ternary operator. It is also known as a conditional operator. Let's write a program to dete...
In JavaScript, the ternary operator also allows conditional chains where the right-side condition chains into another ternary operator. By chaining ternary operators, you effectively write an “if ...else if ... else” conditional chain. But, of course, you have to be careful that chaining the...
三元运算符 Ternary Operator 条件运算符( conditional operator,)(也称为三元运算符( ternary operator))语法是:a ? b : c, wherea是条件,当条件返回true的时候运行代码b,当条件返回false的时候运行代码c。 function checkEqual(a, b) { return a === b ? "Equal" : "Not Equal"; ...
由操作数个数,运算符分一元Unary、二元Binary和三元Ternary。【在JS中只有条件运算符是三元运算符】 表达式Expression:可为直接量、变量、常量、也可以是(运算符、操作符和标点符号)组成的语句。 【直接量:值(如:1233、“abc”、true、[1,2,5]、{width:100,height:200} ….)】最后1个为对象直接量 ...
