ES6 - 关系操作符

假设 A 的值为 10，B 的值为 20。

示例

var num1 = 5;
var num2 = 9;
console.log("Value of num1: " + num1);
console.log("Value of num2 :" + num2);
var res = num1 > num2;
console.log("num1 greater than num2: " + res);
res = num1 < num2;
console.log("num1 lesser than num2: " + res);
res = num1 >= num2;
console.log("num1 greater than or equal to num2: " + res);
res = num1 <= num2;
console.log("num1 lesser than or equal to num2: " + res);
res = num1 == num2;
console.log("num1 is equal to num2: " + res);
res = num1 != num2;
console.log("num1 not equal to num2: " + res);

成功执行以上代码后会显示以下输出。

Value of num1: 5
Value of num2 :9
num1 greater than num2: false
num1 lesser than num2: true
num1 greater than or equal to num2: false
num1 lesser than or equal to num2: true
14 num1 is equal to num2: false
16 num1 not equal to num2: true
