У меня есть запущенный JS-код, который использует HandleBarJs:

 var fs = require('fs');
let template = fs.readFileSync('template.txt', 'utf8')
let submissionJson = fs.readFileSync('submission.json', 'utf8')

var handleBarJs = require('handlebars');
handleBarJs.registerHelper('eq', function (firstParam, secondParam, options) {
    if (firstParam == secondParam) return options.fn(this); else return options.inverse(this);
})
handleBarJs.registerHelper('contains', function (firstParam, secondParam, options) {
    if (firstParam.includes(secondParam)) return options.fn(this); else return options.inverse(this);
})
var compiledTemplate = handleBarJs.compile(template)
var output = compiledTemplate(JSON.parse(submissionJson));
console.log(output);
 

Я хочу написать тот же код в Kotlin JS. Это то, что я пробовал:

 actual class HandleBarService actual constructor() {

    private val handleBars = require("handlebars")

    actual fun generateCertificateString(template: String, data: Any): String {

        println("Input Template:n$template")
//        println("Input Json:n${data}")

        val eqHelper = lambda@ fun(firstParam: String, secondParam: String, options: dynamic) {
            println("firstParam: $firstParam secondParam: $secondParam")
            if (firstParam == secondParam) return options.fn(lambda@ this) else return options.inverse(lambda@ this)
        }
        val containsHelper = lambda@ fun(firstParam: List<String>, secondParam: String, options: dynamic) {
            if (firstParam.contains(secondParam)) return options.fn(lambda@ this) else return options.inverse(lambda@ this)
        }

        handleBars.registerHelper("eq", eqHelper)
        handleBars.registerHelper("contains", containsHelper)

        val handlebarTemplate = handleBars.compile(template)
        val dataTemplate = handlebarTemplate(data)
        println("HandleBar Output:n$dataTemplate")
        return dataTemplate
    }
}

Я получаю желаемый результат с помощью чистого кода JS, но не с помощью Kotlin JS, может кто-нибудь помочь с этим?

Я думаю, что проблема связана с регистрацией помощников. Не уверен, как бы мы написали this ключевое слово внутри lambda, чтобы HandleBarService также не указывать, я просмотрел документацию по этим выражениям
