--description--
使用大于运算符(>
)来比较两个数字。如果大于运算符左边的数字大于右边的数字,将会返回true
。否则,它返回false
。
与相等运算符一样,大于运算符在比较的时候,会转换值的数据类型。
例如
5 > 3 // true
7 > '3' // true
2 > 3 // false
'1' > 9 // false
--instructions--
添加大于
运算符到指定的行,使得返回的语句是有意义的。
--hints--
testGreaterThan(0)
应该返回 "10 or Under"。
assert(testGreaterThan(0) === '10 or Under');
testGreaterThan(10)
应该返回 "10 or Under"。
assert(testGreaterThan(10) === '10 or Under');
testGreaterThan(11)
应该返回 "Over 10"。
assert(testGreaterThan(11) === 'Over 10');
testGreaterThan(99)
应该返回 "Over 10"。
assert(testGreaterThan(99) === 'Over 10');
testGreaterThan(100)
应该返回 "Over 10"。
assert(testGreaterThan(100) === 'Over 10');
testGreaterThan(101)
应该返回 "Over 100"。
assert(testGreaterThan(101) === 'Over 100');
testGreaterThan(150)
应该返回 "Over 100"。
assert(testGreaterThan(150) === 'Over 100');
你应该使用>
运算符至少两次。
assert(code.match(/val\s*>\s*('|")*\d+('|")*/g).length > 1);
