描述
Fail
const foo = index >= 0 ? array[index] : undefined;
const foo = index < 0 ? undefined : array[index];
const foo = index <= array.length - 1 ? array[index] : undefined;
const foo = index > array.length - 1 ? undefined : array[index];
const foo = index >= 5 ? array[index - 5] : undefined;
Pass
const foo = array[index];
const foo = index >= 0 ? array[index] : bar;
I'm not sure if we should add this to no-useless-undefined or add a new rule.
