Before You File a Proposal Please Confirm You Have Done The Following...

• I have searched for related issues and found none that match my proposal.
• I have searched the current rule list and found no rules that match my proposal.
• I have read the FAQ and my problem is not listed.

My proposal is suitable for this project

• My proposal specifically checks TypeScript syntax, or it proposes a check that requires type information to be accurate.
• My proposal is not a "formatting rule"; meaning it does not just enforce how code is formatted (whitespace, brace placement, etc).
• I believe my proposal would be useful to the broader TypeScript community (meaning it is not a niche proposal).

Description

As noted in TSLINT_RULE_ALTERNATIVES , there is not currently an equivalent eslint rule for TSLint's no-unnecessary-callback-wrapper.

Maybe there should be - for the reasons listed on TSLint docs:

There’s generally no reason to wrap a function with a callback wrapper if it’s directly called anyway. Doing so creates extra inline lambdas that slow the runtime down.

Fail Cases

const next = () => {};

debounce(() => {
  next();
});
debounce(() => next());

Pass Cases

const next = () => {};

debounce(next);
