The variable 'thirdElementInArray' was supposed to be the third element in the array. -JavaScript Foundations

This question pertains to Task One of the Creating Arrays Code Challenge.

I've tried a couple different approaches, none of which are correct.

This is what I've tried:

You just have to change the index inside the brackets.

var myArray = ["sugar", "rush", "fix", "it", 3.14, 42];
      var thirdElementInArray = myArray[2];

Type 2 inside [ ] next to myArray, because, as It's asked you want the variable thirdElementArray to be the third one of the array myArray. As we are in an array, the index is 0 based. So we start counting at 0, that's why If we want the variable thirdElementInarray to be the third, we set the value of 2 inside the brackets.

If you want for exemple to set the value of another variable to sugar you would typically do this.

var newVariable =  myArray[0];

To experiment with this quickly, you can open your console and play with it. You'll quickly see the way it works.

thank you, geoffrey

I counted the zero and was using [4] as the value. Thanks for your help and explanation.
