How to check if a list is not empty?
if (serialNumbersList.Any()) //c# expression equivalent
{
// do stuff
}
In javascript there are no lists but arrays, and you can check their length property
if(serialNumberList.length > 0) {
// Do your stuff
}

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.
