I have a js file like this
loader.js
exports.getConfig = function() {
return config;
}
I am loading this file in other file as
var loader = require(__dirname + '/../../loader');
var config = loader.getConfig();
But I am getting error as Object has no method getCOnfig()
I checked the path the path in require is correct

Maybe you have made a circular require, it's not obvious,check it carefully:

I say circular require,I mean suppose you have three module A,B,C. A require B,B require C,C require A. Yes,this is a circular require,this may cause strange error.
I don't know why somebody downvote my answer, I spent hours to figure out what happened when I get this error.I think this question probably is a circular require situation.

Does anyone have any idea why I'm facing this error even though I've clearly specified 'user' as my collection which is a string? Thank you in advance! (Btw I'm tryna modularise all my database Handler into another js file).
The problem is in your module.exports, you're executing the function instead of passing a reference to the function. Try this:
module.exports = {
insertHandler: insertHandler
}
or using ES6
module.exports = {
insertHandler
}

I'm rendering dynamic components inside a dashboard parent item. If there's a component, it renders. If there's not, well... then it doesn't. The problem is that my only dynamic component for now is being rendered twice.
I've tried rendering conditionally, etc, but nothing works.
I'm going to post some code here but you I'm working on a Sandbox, so maybe that's better.
No console errors, just a couple warnings. Any ideas?

You have two <slot></slot> tags in DashboardItem.vue. Remove one ;)

I have data and when I show with sintax console.log(this.state.product) the data show correctly, here the output in console:
now I want to get harga produk from the output, I use this sintax console.log(this.state.product.harga.produk) but I get the error, how to do that? I want to get data that marked red line
it's because your this.state.product still empty (default state declared in constructor).
before console.log make sure this.state.product is filled with the required data.
so you have to turn it into something like this in rendering
if (this.state.product.status && this.state.product.status ==200) {
console.log(this.state.product.data.harga)
}

My code in javascript causes an error at the following line:
var tries:int=GetCallAttemptCount();
The error message says Error in Script Unexpected token : , Line 3
Line 3 is where the error appears. The script was originally in jquery, so I wonder is there a difference in how a variable is declared in Javascript and Jquery?
I'm computer literate, but I am a beginner with Javascript.
Thanks all, Adam
That's not javascript, this looks like typescript, in JS:
var tries = GetCallAttemptCount();

Apologies if this has been asked before but I couldn't find this specific issue.
I've been tasked with analysing a bit of highly obfuscated, and malicious, JS code. I'm trying to get it to run in a VM at the minute just to see exactly what it's up to but I'm getting a syntax error on the first line.
function String.prototype.x(){...
From Chrome's dev console:
Uncaught SyntaxError: Unexpected token .
The red squiggly line shows that the error is being thrown at the first dot (between String and prototype). To be honest, I don't know enough about JS to figure it out but I'm sure one of you lovely lot will know the answer. Why's it thrown and what can I do to fix it?
String is already a class (function with the inbuilt prototype methods) in JS , in order to create methods in its prototype chain you have use as below
String.prototype.reverse = function(){
return this.split('').reverse().join()
}
"hello".reverse() // olleh
