eslint/no-unneeded-ternary Suspicious
What it does
Disallow ternary operators when simpler alternatives exist
Why is this bad?
It’s a common mistake in JavaScript to use a conditional expression to select between two Boolean values instead of using ! to convert the test to a Boolean.
Another common mistake is using a single variable as both the conditional test and the consequent. In such cases, the logical OR can be used to provide the same functionality.
