--description--
使用大于等于
运算符(>=
)来比较两个数字的大小。如果大于等于运算符左边的数字比右边的数字大或者相等,它会返回true
。否则,它会返回false
。
与相等运算符相似,大于等于
运算符在比较的时候会转换值的数据类型。
例如
6 >= 6 // true
7 >= '3' // true
2 >= 3 // false
'7' >= 9 // false
--instructions--
添加大于等于
运算符到指定行,使得函数的返回语句有意义。
--hints--
testGreaterOrEqual(0)
应该返回 "Less than 10"。
assert(testGreaterOrEqual(0) === 'Less than 10');
testGreaterOrEqual(9)
应该返回 "Less than 10"。
assert(testGreaterOrEqual(9) === 'Less than 10');
testGreaterOrEqual(10)
应该返回 "10 or Over"。
assert(testGreaterOrEqual(10) === '10 or Over');
testGreaterOrEqual(11)
应该返回 "10 or Over"。
assert(testGreaterOrEqual(11) === '10 or Over');
testGreaterOrEqual(19)
应该返回 "10 or Over"。
assert(testGreaterOrEqual(19) === '10 or Over');
testGreaterOrEqual(100)
应该返回 "20 or Over"。
assert(testGreaterOrEqual(100) === '20 or Over');
testGreaterOrEqual(21)
应该返回 "20 or Over"。
assert(testGreaterOrEqual(21) === '20 or Over');
你应该使用>=
运算符至少两次。
assert(code.match(/val\s*>=\s*('|")*\d+('|")*/g).length > 1);
