Playing around and trying to custom Module that will hold functions shared across multiple Client Scripts, but I keep getting an

error.SuiteScriptModuleLoaderError

Full Error:

Fail to evaluate script: {"type":"error.SuiteScriptModuleLoaderError","name":"UNEXPECTED_ERROR","message":"missing ; before statement (/SuiteScripts/Employee Equity/plx_cm_employee_equity_module.js#8)","stack":[]}

Client Script Sample:

define(['N/error', 'N/query', 'SuiteScripts/Employee Equity/plx_cm_employee_equity_module'],
    
    function (error, query, plx_cm_employee_equity_module) {

        
        function pageInit(scriptContext) {
            log.debug('pageInit fired')
        }

Custom Module Sample:

define([],
    function () {
        let counter = 0

        const incrementValue = () => {
            counter++
        }

        const getValue = () => {
            return counter
        }

        return {
            incrementValue : incrementValue,
            getValue : getValue
        };
    });

Client scripts don’t support 2.1 syntax yet. Your module uses arrow notation instead of an explicit function declaration.

ahh, thank you

You can have 2.1 client scripts as of 2021.2 IIRC
