Is there a rule for preferring if / else to initialising a variable and then overriding it?

[guilhermesimoes]

Basically, prefer this:

let unitialisedVariable;

if (someCondition) {
  unitialisedVariable = someValue;
} else {
  unitialisedVariable = someOtherValue;
}

over this:

let unitialisedVariable = someOtherValue;

if (someCondition) {
  unitialisedVariable = someValue;
}

Is there a rule for this situation?

No there isn’t. You can see all core rules here https://eslint.org/docs/rules/
