--description--
当if
语句的条件为真,大括号里的代码执行,那如果条件为假呢?正常情况下什么也不会发生。使用else语句,可以执行当条件为假时相应的代码。
if (num > 10) {
return "Bigger than 10";
} else {
return "10 or Less";
}
--instructions--
请把多个if
语句合并为一个if/else
语句。
--hints--
你应该只有一个if
表达式。
assert(code.match(/if/g).length === 1);
你应该使用一个else
表达式。
assert(/else/g.test(code));
testElse(4)
应该返回 "5 or Smaller"。
assert(testElse(4) === '5 or Smaller');
testElse(5)
应该返回 "5 or Smaller"。
assert(testElse(5) === '5 or Smaller');
testElse(6)
应该返回 "Bigger than 5"。
assert(testElse(6) === 'Bigger than 5');
testElse(10)
应该返回 "Bigger than 5"。
assert(testElse(10) === 'Bigger than 5');
不要修改上面和下面的代码。
assert(/var result = "";/.test(code) && /return result;/.test(code));
--seed--
--seed-contents--
function testElse(val) {
var result = "";
// Only change code below this line
if (val > 5) {
result = "Bigger than 5";
}
if (val <= 5) {
result = "5 or Smaller";
}
// Only change code above this line
return result;
}
testElse(4);
--solutions--
function testElse(val) {
var result = "";
if(val > 5) {
result = "Bigger than 5";
} else {
result = "5 or Smaller";
}
return result;
}
