Define a variable car, an Object with the following properties:
model of ’Nissan’
color of ’Blue’
numWheels, a number of wheels. Value is 4
The object should also have the following method:
Method drive that returns ’Vroom!’
What I tried:
const car = {
model: 'Nissan',
color: 'Blue',
numwheels: 4,
drive: function() {
return'Vroom!'
},
}
console.log (car)
What I got:
{
model: 'Nissan',
color: 'Blue',
numwheels: 4,
drive: [Function: drive]
}
I have changed “console.log (‘Vroom!)”
To “return ‘Vroom!’”
And I get the result I need

Method drive that returns Vroom!
In your code, your drive() method is logging Vroom! to the console, not returning it as the value of the function. Change console.log('Vroom!') to return 'Vroom!' and use console.log(car.drive()) instead of console.log(car). Your complete code should look something like this:
const car = {
model: 'Nissan',
color: 'Blue',
numwheels: 4,
drive: function() {
return 'Vroom!';
},
}
console.log (car.drive());

I am using javascript.I have a json data set. I am trying to convert in a particular way. Can someone write the function so that I can convert it.
Given Json data:
{
"members":[
{
"value":"view",
"code":"reservations"
},
{
"value":"view",
"code":"dashboard"
}
]
}
Trying to convert in:
{
"members": [
{
"view_reservation": true,
"edit_reservation": true,
"create_reservation": true,
"delete_reservation": true
},
{
"view_dashboard": true,
"edit_dashboard": true,
"create_dashboard": true,
"delete_dashboard": true
}
]
}
Can someone write a function in javascript to convert it...

const data = JSON.parse(jsonData);
data.members = data.members.map(member => ({
`${member.view}_${member.code}`: true,
`edit_${member.code}`: true,
`create_${member.code}`: true,
`delete_${member.code}`: true
}));

you multiply output, we can just assume, that you always get 4 rows (CRUD-like)
Anyway, the approach of converting your object/array to the desired output can be done using something like this (where x is your current object):
var y = { "members": [] };
x.members.forEach(element => { y.members.push({ [element.code + '_' + element.value]: true}) } );
you can just edit the new object in the y.members.push to your desire

enter code hereJS Code:
DOCUMENTS = [{
name: 'I551Indicator',
text: ‘School Document’,
},
{
name: 'I553Indicator',
text: ‘Birth Certificate’,
}
];
User_Selected_Documents = [{
I551Indicator: false,
I553Indicator: true
}];
From the DOCUMENTS array, I have to display the text of the document for the keys whose value is true in User_Selected_Documents array.
I tried the below, seems to get the text
const test = DOCUMENTS.map(doc => doc).map(doc => doc.name).filter(DOCUMENTS.map(selctedDocuments));
trying to find the key whose value is true from User_Selected_Documents.filter(selectedDocument => Object.values(selectedDocument) === true)
dosen't seem to work.
EXPECTED RESULT: I this case it is Birth Certificate since I553Indicator is true

You need to use filter and then map. Below code works:
DOCUMENTS = [{
name: 'I551Indicator',
text: 'School Document',
},
{
name: 'I553Indicator',
text: 'Birth Certificate',
}
];
User_Selected_Documents = [{
I551Indicator: false,
I553Indicator: true
}];
const result = DOCUMENTS.filter(x => User_Selected_Documents[0][x.name]).map(x => x.text)
console.log(result[0])

I am using a API and that api give me list of users detail, I want to filter the details of user according to logged in user id, How can i filter data using specific id from array.
Any solution appreciated...!

I am considering you are getting array of objects.
suppose you have array a. then
for (var i =0;i<a.length,a++){
if(a[i].user_id == <specific user_id>){
// your code
break;
}
}

It's tough to make a suggestion without more information, but for example, if your data looks like apiData below, then you could simply make a new array and push all the items with the chosen userId property value to it:
const apiData = [
{ userId: 1, favoriteColor: "blue" },
{ userId: 2, favoriteColor: "yellow" },
{ userId: 1, favoriteFood: "pasta" },
{ userId: 2, favoriteFood: "cookies" },
];
const filteredData = [];
apiData.forEach(function(item){
if(item.userId == 1){
filteredData.push(item);
}
});
console.log(filteredData);

include underscore.js in your app .
._filter(x => x.apiResopnseId == yourId); //return filtered users detail

Filter array by nested value that meets certain condition in Vue

I am trying to filter an Array that contains nested array of Objects. I would like for the v-for to only show those objects that meet certain condition. I have created a JSfiddle Click Here
The part that confuses me is that each enagagement could have 1 object or 3 objects, and I don't know how to check value conditions for each nested object.
I want to only show Engagements with questions that are not answered. I am using a boolean value to represent whether the question is answered or not.
This is the v-for
<div id="app">
<h2>Engagements:</h2>
<div>
<div v-for="(engagment, index) in filteredQuestions" :key="index">
<li v-for="question in engagment.questions" :key="question.id">
<span>{{ question.id }},</span>
<span> {{ question.question}} </span>
<span><input type="checkbox" v-model="question.answered"></span>
</li>
</div>
</div>
</div>
This is the Script and Data
new Vue({
el: "#app",
data: {
engagements: [
{
id: 1,
text: "1040",
questions: [
{
id: 1,
question: 'this is a question',
answered: 0
},
{
id: 2,
question: 'this is a question',
answered: 1
},
]
},
{
id: 2,
text: "1040",
questions: [
{
id: 3,
question: 'this is a question',
answered: 0
},
]
},
]
},
computed: {
filteredQuestions() {
const engagement = this.engagements.filter((engagement) => {
return engagement.questions.filter((question) => question.answered === 0)
})
return engagement
}
}
})
Currently no matter how I format the filteredQuestions method it will either render the entire list or show nothing. Please view the jsfiddle I included at the top of this post!

You're filtering the engagements based on them having 1 or more unanswered questions, but the v-for is still rendering all questions inside those engagements.
WRONG: Add v-if="question.answered==0" to the <li> element to only show unanswered questions. (This is wrong practice, I found out: see lint error here. You should not use v-if and v-for on the same element.)
CORRECT:
In this case extend your filteredQuestions computed value function to only return questions without answers. (Now you are just filtering the engagements based on that, but still returning all of the questions.)
Your computed value function could be:
filteredQuestions() {
return this.engagements
// Return a modified copy of engagements..
.map((engagement) => {
// ..with all answered questions filtered out..
engagement.questions = engagement.questions.filter((question) => question.answered === 0);
return engagement;
})
// ..and only return engagements that have (unanswered) questions left
.filter((engagement) => engagement.questions.length !== 0);
}

The above option not work if you are trying to find the first level's array and nested item in array
For example engagements's name and questions sub item name because the filter will do the last match
If you are trying to find matches on nested array for example on names should do the next code
return this.content.filter((sub) => {
//for save the status
let show = false
//find in nested: themes
sub.Themes = sub.Themes.filter((theme) => {
if (reg.test(theme.name)) {
show = true
return true
}
return false
})
//if was finded match in themes show the subject or if the subject name match too
if (show === true || reg.test(sub.name)) {
return true
}
return false
})
