Research direction

Start by reading Part 3.2 and comparing its .find(value) syntax with the official documentation's .find(value, start, end) signature. Clarify whether start and end are optional parameters, then ensure the course explanation answers why the shorter form is shown; done when the syntax and parameter behavior are clear.

Description

I have a question about the string.find() method in Part 3.2

Image

In the course material, the syntax is explained as:
.find(value)

But according to the official documentation, the full syntax is:
.find(value, start, end)

Why does the course only show .find(value) and not .find(value, start, end)?
Is it because start and end are optional parameters?
