Regular Expressions - Check For Mixed Grouping of Characters

[SebZG]

I’m trying to understand the solution given.

let myString = “Eleanor Roosevelt”;
let myRegex = /(Franklin|Eleanor) (([A-Z].?|[A-Z][a-z]+) )?Roosevelt/;
let result = myRegex.test(myString);

There is a space here ) )?
When I check without it, it doesn’t pass. What is that space doing? Is it checking for white space?
