var charArray=[a,b,c]
I want to have a new array as following:
var charArrayNew=[a, ab, abc]
Please suggest how to get the result of charArrayNew in ES6 Javascript.
You could do this:
const charArray=['a','b','c'];
const answer = charArray.map((_,i,ar)=>ar.slice(0,i+1).join(""));
console.log(answer);
// or, alternatively:
fn=(ar,res=[])=>(
ar.reduce((a,c)=>(res.push(a+=c),a),""),res );
console.log(fn(charArray))

I am trying to declare an integer Array but don't know how to do this. Is it possible to declare a int array in Vue.
In your script , just add this below :
data(){
return {
your_array : [1,2,3,4,5,6]
}
}
your_array is just an example, the variable name can be any anything.

For example if we have:
let r = JSON.parse('{"o": {"name": "foo","lastName": "boo"}}');
Can we now do console.log(r.o.name); and get foo on the console?
Yes. Here's a runnable example:
let r = JSON.parse('{"o": {"name": "foo","lastName": "boo"}}');
console.log(r.o.name)

Hello i have an object in JavaScript which contains this:
{Coc Coc={30daysAgo=1}, Mozilla={30daysAgo=1}, BlackBerry={30daysAgo=1}, Safari={30daysAgo=140}, Firefox={30daysAgo=192}, YaBrowser={30daysAgo=6}, Internet Explorer={30daysAgo=72}, Safari (in-app)={30daysAgo=40}, Android Browser={30daysAgo=3}, Chrome={30daysAgo=1387}, SeaMonkey={30daysAgo=1}, Edge={30daysAgo=7}, Opera={30daysAgo=7}}
How can i insert in a variable only the names of the browsers without the rest?
e.g var browsers = Mozilla,BlackBerry,Safari etc...
Try this:
var a = {"Coc Coc":{"30daysAgo":1}, Mozilla:{"30daysAgo":1}, BlackBerry:{"30daysAgo":1}, Safari:{"30daysAgo":140}, Firefox:{"30daysAgo":192}, YaBrowser:{"30daysAgo":6}, "Internet Explorer":{"30daysAgo":72}, "Safari (in-app)":{"30daysAgo":40}, "Android Browser":{"30daysAgo":3}, Chrome:{"30daysAgo":1387}, SeaMonkey:{"30daysAgo":1}, Edge:{"30daysAgo":7}, Opera:{"30daysAgo":7}};
var browsers = Object.keys(a).join(",");
Result:
Coc Coc,Mozilla,BlackBerry,Safari,Firefox,YaBrowser,Internet Explorer,Safari (in-app),Android Browser,Chrome,SeaMonkey,Edge,Opera

Consider:
var playlist = {"bad romance":"gaga", "we cry":"the script"};
How can I get string "gaga" from my code? What is the name of my array in JavaScript programming?
Try Object instead of Array:
var playlist = {"bad romance":"gaga", "we cry":"the script"};
alert(playlist["bad romance"]); //gaga
