WGU Courses and Certificates Web-Development-Applications Question # 14 Topic 2 Discussion

The data type of the variable a is determined by the value assigned to it. In JavaScript, if a value is enclosed in double or single quotes, it is treated as a string.

Variable Assignment:

Given the code:

var a = "true";

The value "true" is enclosed in double quotes, making it a string.

Explanation:

Option A: Boolean is incorrect because the value "true" is a string, not a boolean.

Option B: String is correct because the value is enclosed in double quotes.

Option C: Object is incorrect because the value is a primitive string.

Option D: Undefined is incorrect because the variable a is assigned a value.
