Rule proposal: `no-unnecessary-type-casting`
See original GitHub issueFAIL
if (Boolean(foo)) {}
if (!!foo) {}
foo(Boolean(bar) ? 1 : 2)
const foo = Boolean(bar);
if (foo) {}
Not sure about the last one, the example seems need fail, but this and this seems more readable with type-casting.
PASS
if (foo) {}
foo(bar ? 1 : 2)
Got the idea from #616 L167 L195, examples only shows Boolean type-casting, haven’t thought about other types.
