thanks for feedback gentlemen, i just handled the test case for that problem right after the function ran and boom.

Hi
I've an array like this
var ab = [
{weight: 1, answer: "3"},
{weight: 2, answer: "5"},
{weight: 1, answer: "2"},
{weight: 2, answer: "3"},
{weight: 1, answer: "4"},
];
and I want to multiply this value like this (1 x 3) x (2 x 5) x (1 x 2) x (2 x 3) x (1 x 4) = 1440 using javascript
Can anyone help me
?
dimtabu
@taburetkin
let score = ab.reduce((memo, item) => memo += item.weight * item.answer, 0)
ah, there is multiply
let score = ab.reduce((memo, item) => memo *= item.weight * item.answer, 1);

Does anyone know how to use the Webster Dictionary API? I could use some pointers. I read the documentation, but I am still confused as heck.
I want to create a Writing Prompt Generator, and I think the API can help instead of me making a database of words

Hi. I needed your thoughts on the use of constants as in the code below.

function createUrl(urlPath) {
    const endpoint = url.parse(env.config.get('myEndpoint'));
    endpoint.pathname = path.posix.join(endpoint.pathname, urlPath);
    return endpoint;
}

The above snippet won't throw an error but is it okay to declare some object as a const even if I know that I would be making some change to it?

I am mapping array of objects. and also displaying obj.quantity on browser
I am also passing obj in addQuantity(obj) and subQuantity(obj)
However increment and decrement of quantity is not reflected on browser that obj.quantity

How can I generate same code block above 5times but with different images number like this one has 25b.jpg. So I am unable to generate this same block dynamically 26b.jpg, 27b.jpg ... and so on. I tried with js

If your version of js supports template strings then replace the fixed values with
${value} then loop over the various values

Hi, can someone please give me a piece of advice. I need to built a very heavy, complicated web application with multiple web pages(almost 60 pages).I already have a theme with me. I want to use a framework like angular which could make life a bit easier but that website need very good SEO. using angular universal, it might be possible but it is gonna use jquery and a lot of query selector which will not work in angular universal. so if I go with the plain javascript approach, how am I gonna handle routing and all.

Hey guys, any ideal how I improve the readability of this object?
        var routes = {
            get main() { return Route('', {
                customer: Route('/customer/:id', {
                    get cart() { return Route('/cart')() },
                }),
                edit_realty: Route('/realty/:id', {
                    config: Route('/config/:setting', {
                        get look() { return Route('/look')() }
                    })
                })
            })()}
        }
Im building an route manager to my team but this config obj is unredable and I dont know how to improve this
this is the route function:
        function Route(path, children) {
            return function(param) {
                url += path.replace(/:id|:setting/g, param);
                return children;
            };
        }

can I return common jquery http response to some other function
I want to write common post method
will pass the url and json data
Stephen James
@sjames1958gm
Since http is a asynchronous you could wrap it in a promise and then use async/await and pass the response back in the promise resolve. The browser fetch function might be an alternative.
Shekhar Ramola
@shekharramola
browser fetch..yes but it do not work in IE?
Stephen James
@sjames1958gm
Possibly not

var xhr = $.ajax({...});
mySuperFunction(xhr);

function mySuperFunction(xhr) {
  xhr.then(() => .... );
}

what wrong with this approach?

Shekhar Ramola
@shekharramola
@taburetkin , this is cool but I try to follow DRY(Do not repeat) wherever possible.
dimtabu
@taburetkin
Its not clear what do you want to achieve
Shekhar Ramola
@shekharramola
am I doing anything wrong?
 addDynamicHTML('particularId', data.data[i].title);
function addDynamicHTML(selectedElementId, template) {
  console.log(selectedElementId);
  console.log(template);
  if (document) {
    console.log(document.getElementById(selectedElementId));
    document.getElementById(
      JSON.stringify(selectedElementId)
    ).innerHTML = template;
  }
}
 console.log(document.getElementById(selectedElementId));
above statement will say, it is null though it shouldn't be. just a plain synchronous function

@taburetkin
you can work with dom by js only after dominteractive event
and for some browsers after dom loaded event
Shekhar Ramola
@shekharramola
I am creating dom element dynamically.
like this
    var tdDeliveryTerms = createElement('td');
    addClass(tdDeliveryTerms, 'tableTitle');
    addClass(tdDeliveryTerms, 'fontSize12');
    var particaularDiv = divCreator();
    addClass(particaularDiv, 'fontMedium');
    addClass(particaularDiv, 'title');
    particaularDiv.setAttribute('id', 'particularId');
    console.log(particaularDiv);
    addDynamicHTML('particularId', data.data[i].title);
dimtabu
@taburetkin
document in all browsers is not falsy. so your if is useless
if your DOM not ready, you get null, so you have to wait for document completely loaded for working with dom.
Shekhar Ramola
@shekharramola
couldn't attach an event listener due to performance issue so I tried another way. seems like working.
function addDynamicHTML(selectedElement, template) {
  console.log(selectedElement);
  console.log(template);
  var text = document.createTextNode(template);
  selectedElement.appendChild(text);
}

@syedsimanta03 Since I mostly dabble in NodeJS, all platforms are equally suited. Linux is a good option for server-side, and Windows has worked fine for me as my dev platform.
