Expert Solution

Step 1

Parameters in a function definition are placed in parantheses.

Explanation: Parameters all always in parantheses because it is a valid syntax in javascript. If you use braces or single or double quotes you will get a syntax error.

A sample function definition in javascript is as follows:

function mul(a,b){ //Here a and b are parameters
return a*b;
}
