Front End Web Development Techdegree Student 8,288 PointsJavaScript Loops, Arrays and Objects Challenge 1
Hi there,
I'm suppose to create a For Loop to log numbers from 4 to 156, then use the console.log method to print out the numbers. The challenge keeps saying I have a syntax error and won't let me pass.
Can someone point out to me where and what the error is? Thank you!
var numbersAll = '';
var firstNumber = 4;
for (var = i ; i <= 156 ; i += 1 ) {
numbersAll += i + firstNumber ;
}
console.log(numbersAll);

All you need to do is this:
for (var i = 4; i < 156; i++) {
console.log(i);
}
Good luck! ~Alex

console.log(i);
I hope this helps.

Thank you so much for your input ! Yes I realised i set var = i, which is wrong.
Thank you for pointing that out! Appreciate it very much ! =)

First, you had some syntax error in the for loop conditions. "for (var = i ; i <= 156 ; i += 1 )" , here i guess you mean "for(var i= firstNumber; i<= 156 ; i+= 1)";
Second, you put "console.log(...)" outside of the for loop, so it will only be executed once.
There are other errors, but those are more like logic error.

23,118 Pointsyou need to either change the number to 157 or add an <= in your condition.

65,469 PointsThis code challenge is a little weird. I know that this will count from 4 to 156, but the challenge is expecting "i < 156", which is 4 to 155.
