Optional chaining (?.) in JS
#js
The (?.) operator functions similarly to the . chaining operator, except that instead of causing an error if a reference is null (null or undefined), the expression short-circuits with a return value of undefined. When used with function calls, it returns undefined if the given function does not exist.
