javascript - Require user to choose 'boy' or 'girl' -



javascript - Require user to choose 'boy' or 'girl' -

i trying user respond question "are boy or girl?" 1 of 2 choices , forcefulness them take 1 or other.

i think heading in right direction whenever run code, hiccups if choosing sec option.

what doing wrong?

var gender = prompt("are boy or girl?").tolowercase(); while (gender !== ("boy" || "girl")) { gender = prompt("please respond boy or girl. now, boy or girl?"); }

the proper status be

while (gender !== 'boy' && gender !== 'girl'){

that's because ("boy" || "girl") end "boy", hence while while(gender !== 'boy'). || in case called "default" operator, clever utilize of logical or . if value on left side truthy, utilize left side value. otherwise, evaluate (hence "default") right side.

javascript prompt
