@studnicky/v8/inline-functions

Same allocation-churn problem as inline arrow functions, for function expression values instead of arrow functions: a dispatch map built once at module scope or as a static class field allocates each function value a single time, while the same literal rebuilt inside a function or method body, or in a non-static instance field, re-allocates every function value on every call. Extract the handler to a named function, or hoist the map itself to module or static scope. Property values named transform or transformAsync are exempt, as are references to an already-named function.

Fixable: No · Options: No · Suggested severity: error

✗ Incorrect

function build() {
  return {
    a: function () { return 1; }
  };
}

✓ Correct

const map = {
  a: function () { return 1; }
};
