大于 (>)

¥Syntax

x > y

¥Description

使用与 少于 运算符相同的算法来比较操作数，只不过交换了两个操作数。x > y 通常等同于 y < x，只不过 x > y 在 y 之前将 x 强制为原语，而 y < x 在 x 之前将 y 强制为原语。由于强制转换可能会产生副作用，因此操作数的顺序可能很重要。

¥The operands are compared using the same algorithm as the Less than operator, except the two operands are swapped. x > y is generally equivalent to y < x, except that x > y coerces x to a primitive before y, while y < x coerces y to a primitive before x. Because coercion may have side effects, the order of the operands may matter.

¥Examples

¥String to string comparison

"a" > "b"; // false
"a" > "a"; // false
"a" > "3"; // true

¥String to number comparison

"5" > 3; // true
"3" > 3; // false
"3" > 5; // false

"hello" > 5; // false
5 > "hello"; // false

"5" > 3n; // true
"3" > 5n; // false

¥Number to Number comparison

5 > 3; // true
3 > 3; // false
3 > 5; // false

¥Number to BigInt comparison

5n > 3; // true
3 > 5n; // false

¥Comparing Boolean, null, undefined, NaN

true > false; // true
false > true; // false

true > 0; // true
true > 1; // false

null > 0; // false
1 > null; // true

undefined > 3; // false
3 > undefined; // false

3 > NaN; // false
NaN > 3; // false
