codemodscript to refactor `useEffect` with empty array to `useEffectOnce` without an array arg

callexpressions.js

module.exports = function (file, api) {
  const j = api.jscodeshift;
  const { CallExpression, Identifier } = j;

  return (

        callee: {
          name: "useEffect",
        },
      })
      .filter((node) => {
        return (
          // is a useEffect with 2 arguments
          node.value.arguments.length === 2 &&
          // 2nd argument is an array type
          node.value.arguments[1].type === "ArrayExpression" &&
          // said array argument is an empty array
          node.value.arguments[1].elements.length === 0
        );
      })
      // operate on useEffects that have an empty dependency array
      .forEach((node) => {
        // refactor the function name
        node.value.callee.name = "useEffectOnce";

        // remove the 2nd argument to this function
        node.value.arguments = [node.value.arguments[0]];
      })
