Happy Coding

Using the DOT instances

I am learning about classes, and would like to know what the length parameter means when used in the following script.
“circles.length” It is used in this loop
for (let i = 0; i < circle.length; i++){
let c = circles[]

Out of curiosity where did you find that code? Looks like it has a couple of typos!

My guess is that the for loop is meant to reference a variable called circles which is probably an array. Arrays hold multiple values, and the length property tells you how many values are in an array.
