Why is my array.map() not returning a new value when using spread operator?

I want a user to be able to put his info about their book and push it into the library. I can do this when it comes to display but I want to have it saved as a new object in javascript. A new array 'newBooks' that I created don't return a new value, it stays the same even though I used spread operator which is supposed to change the value. Could someone tell me what's going on?

Your book is wrong formated
let info = {
id: 1, imageUrl: '',
id: 2, title: 'Title:',
id: 3, author: 'Author:',
id: 4, pages: 'Pages:'
}
console.log( info )
is the same as
let info = {}
info.id = 1
info.id = 2
info.id = 3
info.id = 4
info.title = ....
there could be only one info.id propertie
I lost time understanding the purpose of your code, but I suggest you get inspired by this way of coding...

Okay, I figured it out. It seems like I have to add an ID to the whole object(It was 4 before and I changed it to ID: 1. Then I added return {...newBook, author: inputAuthor.value, title: inputTitle.value, pages: inputPages.value} in a new array.

nested object is not inserted into table using javascript

I am new to javaScript
here in this code, I'm trying to add companyDetails(nested object of productDetails) in the table by its id.
Like, for id 1 I want to add companyDetails then in the input field of id enter id 1 and insert details in the given input fields
so my problem is that companyDetails(date,address,companyName)is not displayed in the table after adding its value for entered id
let productDetails = [

How to set Check attribute for a radio element?

I'm trying to make a quiz app using JavaScript and jQuery, if I click on a radio button am setting an attribute as checked but if I move on to another question and click on any radio button there in the previous question radio button selects get removed how can I make sure that it is selected even if I move on to any question and select options there. I guess its happening because I have common name on the radio button Can someone help me out?

CodePen http://codepen.io/kannant14/pen/peLOXG

One way to solve it is to name your radiobuttons in the render function with a question index like:
var options="<div class='radio'><label><input type='radio' name='optradio"+i+"' questionno="+datas[i].id+" value="+datas[i].options[j]+">"+datas[i].options[j]+"</label></div>"
and the same in the selectanswers function:
selectanswers:function(temp) {
for(var i=0;i<datas.length;i++) {
if(datas[i].id==temp){
datas[i].selectedanswer=$('input[name=optradio'+i+']:checked').val();
}
}
}
then you just need to keep track of the question index when checking the correct answers.

Passing data into chart using HTML and JavaScript

The following code is used to display a chart. The problem is the "data" is hard coded in. How can I change this so that the chart displays values which are displayed using:
<div id="name"> </div>
<div id="testscore"></div>
The above 2 div's contain dynamic values. I want to display these values in the chart.
<script type="text/javascript">
window.onload = function () {
var chart = new CanvasJS.Chart("chartContainer",
{
// title:{
// text: "Olympic Medals of all Times (till 2012 Olympics)"
// },
animationEnabled: true,
legend: {
cursor:"pointer",
itemclick : function(e) {
if (typeof (e.dataSeries.visible) === "undefined" || e.dataSeries.visible) {
e.dataSeries.visible = false;
}
else {
e.dataSeries.visible = true;
}
chart.render();
}
},
axisY: {
title: "Time"
},
toolTip: {
shared: true,
content: function(e){
var str = '';
var total = 0 ;
var str3;
var str2 ;
for (var i = 0; i < e.entries.length; i++){
var str1 = "<span style= 'color:"+e.entries[i].dataSeries.color + "'> " + e.entries[i].dataSeries.name + "</span>: <strong>"+ e.entries[i].dataPoint.y + "</strong> <br/>" ;
total = e.entries[i].dataPoint.y + total;
str = str.concat(str1);
}
str2 = "<span style = 'color:DodgerBlue; '><strong>"+e.entries[0].dataPoint.label + "</strong></span><br/>";
str3 = "<span style = 'color:Tomato '>Total: </span><strong>" + total + "</strong><br/>";
return (str2.concat(str)).concat(str3);
}
},
data: [
{
type: "bar",
showInLegend: true,
name: "Black",
color: "#000000",
dataPoints: [
{ y: 0.18, label: "Name"},
{ y: 0.12, label: "Name 1"},
{ y: 0.59, label: "Name 2"},
{ y: 1.15, label: "Name 3"},
]
},
]
});
chart.render();
}
</script>

You can simply call
var data = document.getElementById('name').value;
var data2 = document.getElementById('testscore').value;
If it's a single value, it would work; otherwise, you need to do it this way:
var array = $('#your.id').data('stuff');
Here, "stuff" is nothing but
<div data-stuff="some data" ></div>
Or, create an array by:
var array = new Array();
and finally, store the data into the array.

Obviously I'm very new to AngularJS and am likely doing everything wrong. I have searched for similar solutions to learn from but can't find anything that is doing quite what I'm working on. The main issue I am having at this point is if I include the code that limits genres to only those available in the sub-set of movie results it loops infinitely, and no matter which angle I take I can't seem to get it all to work together. Some guidance would be greatly appreciated, even if its just to recommend a better structure, I'm sure I'm putting too much into the controller among other fails.
Other unfinished portions:
- views for each type of content
- re-size elements on window size
- Drag and scroll behavior
