Expected ;


#1

var j = 0

for (var i = 1; i < 15; i *= 3) {
console.log("For")
};

while (j < 10) {
console.log("while")
var j = j + 2
};

do {
console.log("do...")
j = j + 2
} while (j < 12)


#2

At the top where you're declaring your variable j, you forgot the semi colon.

var j = 0;

#3
var j = j + 2

no var on this line as it is already declared at the top of your program. The rest seems to be ok although you could add some semicolons after statements like this:

var name = value;
name = value;
functionCall();

for example:

var j = 0
j = j + 2
console.log("do...")
