What is the purpose of parentheses in JavaScript?
An example of an AI chatbot conversation about the use of parentheses in JavaScript.
What is the purpose of parentheses in JavaScript?
Parentheses in JavaScript are used for grouping expressions, controlling the order of operations, and defining function parameters.
Can you give me an example of how parentheses affect the order of operations?
Sure! In the expression 2 + 3 * 4, the multiplication happens first, resulting in 2 + 12, which equals 14. If you use parentheses like this: (2 + 3) * 4, it changes the result to 5 * 4, which equals 20.
What about their use in functions?
In functions, parentheses are used to enclose parameters. For example, in function add(a, b), the parentheses contain the parameters a and b.
Are there any other uses for parentheses in JavaScript?
Yes, parentheses are also used in control flow statements like if and while, as well as in immediately invoked function expressions (IIFE).
