I do not understand what they mean by update the variable.

You can think of a variable as simply a container in which to store information, like tupperware for left over food. If you want to update the contents of any given container, you simply change what's inside of it. If you have tupperware with chicken, but tomorrow you want salad, you replace the chicken with the salad, i.e. you "update" the contents of the container. In this particular code challenge, they are asking you to update what is inside of the variable called "quickLength" to be the length of the string that is contained in the variable "quick":

var quickLength = quick.length;

Hope this helps make some more sense of things!
