I found a problem in :https://developer.mozilla.org/zh-CN/docs/Learn/JavaScript/Building_blocks/conditionals

HI, as the picture showed i just found a problem in a test may be confusing for some noob like me.maybe we should change the select’s value into lowercase.

I think it’s okay. Quoting from the task: (italic and bold by me)

For each case, the choice should equal one of the possible values that can be selected, that is, white, black, purple, yellow, or psychedelic. Note that the values are case sensitive, and should equal the <option> element value values rather than the visual labels.

Yes,but in this case we don’t have html code,there’s only visual tag.At first time,I thought the value of those options should be same as the visual labels,and i wrote my js code using the ‘White,Black,Purple…’,that waste me time untill i give up writing code to wtach the answer.
