Using the value of an object as a parameter for another object in Javascript

Assuming I have the following variables:

var key = "Section";
course.key = "101";

After running this code, I encounter an error stating that course.key is unidentified. My intention is to set course.Section = "101". Is there a way to pass the value of key in the second line?

Answer №1

The key property in the course object is currently undefined. To assign a value, use bracket notation.

course[key] = "101"

This is equivalent to

course["Section"] = "101"
