Examples of correct code for no-unneeded-ternary

This is a discussion/question.

Why are

var a = x ? y : x;

var a = x ? x : 1;

considered correct?

cf http://eslint.org/docs/rules/no-unneeded-ternary#rule-details

You could write them as

var a = x && y;

var a = x || 1;

What am I missing?

This rule disallow ternary operators when simpler alternatives exist.

I agree, it would be nice if the rule caught these.

Other cases:

!x ? y : x;
!x ? x : y;

// gets fixed to

x || y;
x && y;

I think the rule should still report MemberExpressions, even if it doesn’t autofix them. Getters with side-effects are very rare, so the report would still be useful in the vast majority of cases.

Seems like an oversight to me: should be fixed.
