Note
Definition

Default values are values that are taken up by the parameters of a function when no corresponding argument is passed into the function call.

We can assign default values to parameters using the syntax:

function funcName(parameter1 = value1, parameter2 = value2, …) {
  // your code here …
}

Example:

12345
function sum(a = 5, b = 10) { return a + b; } console.log(sum()); // Output: 15
copy
