Next, change the color of each child paragraph to blue.
(Remember: paragraphs is a collection of elements, so you'll first need to use a loop to access each element in the collection.)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ is the question my code is getting an error
var section = document.querySelector('section');
var paragraphs = section.children;
for (let i = 0; i < paragraphs.length; i += 1) {
color = "blue"(paragraphs[i]);
}

- the code to access the paragraph needs to be on the left side of the assignment.
- the properties should be accessed on the paragraph element
- only the color itself should be on the right side
- "color" is a sub-property of the "style" property

Steven Parker
231,236 PointsIn an assigment, the "=" is the assignment operator, the left side of it is where you put the thing that is being assigned, and the right side is where you put the value being given to it.
ā this is the left side ā = ā this is the right side

Full Stack JavaScript Techdegree Student 5,459 PointsIs this the index (paragraph[i]); ?
Steven Parker
231,236 PointsThe index is the value in brackets [i]

231,236 PointsYou're missing the index on the left side of the assignment. And there should be nothing on the right side except for "blue".
