## E0122: missing catch or finally clause for try statement

A `try` statement has a list of statements followed by an optional `catch` block followed by an optional `finally` block. It is a syntax error to omit both the `catch` block and the `finally` block:

    async function readConfig(configFilePath) {
      try {
        let data = await fs.promises.readFile(
          configFilePath,
          "utf-8",
        );
        return parseConfig(data);
      }
    }

    let recursionDepth = 0;
    function recursionExample() {
      if (recursionDepth > 100) {
        throw new Error("too much recursion!");
      }
      recursionDepth += 1;
      try {
        recursionExample();
      }
    }

To fix this error, remove the `try` keyword:

    async function readConfig(configFilePath) {
      let data = await fs.promises.readFile(
        configFilePath,
        "utf-8",
      );
      return parseConfig(data);
    }

Alternatively, add a `catch` block after the `try` block:

    async function readConfig(configFilePath) {
      try {
        let data = await fs.promises.readFile(
          configFilePath,
          "utf-8",
        );
        return parseConfig(data);
      } catch (error) {
        if (error.code === 'ENOENT') {
          return {};
        } else {
          throw error;
        }
      }
    }

Alternatively, add a `finally` block after the `try` block:

    let recursionDepth = 0;
    function recursionExample() {
      if (recursionDepth > 100) {
        throw new Error("too much recursion!");
      }
      recursionDepth += 1;
      try {
        recursionExample();
      } finally {
        recursionDepth -= 1;
      }
    }
