Is the presence of the second optional chaining causing any negative impact?
let flag = somePotentialNullObj?.someNumProp > 0 && somePotentialNullObj?.someOtherProp;
The second optional chaining is unnecessary as it works the same without it:
let flag = somePotentialNullObj?.someNumProp > 0 && somePotentialNullObj.someOtherProp;
If it comes after the &&, somePotentialNullObj should not be null or undefined, so we shouldn't need to check again with ?, right?
I agree that incorporating optional chaining into the latter part of the statement is crucial.
In scenarios where someProp is absent, the initial ?. disregards the comparison and results in an undefined value. This causes the second half of the && to be bypassed. If we reach the latter portion of the expression with a &&, it indicates that someProp has been located.
I am uncertain about how efficiently the interpreter handles either suggestion by the OP. At first glance, the second suggestion appears to require less processing power on average.
