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))

So my codes are like below;
$.getJSON('https://api.myjson.com/bins/gxs81',function(data){
$.each(data.employees,function(i,emp){
$('ul').append('<li>'+emp.firstName+' '+emp.lastName+'</li>');
});
I have multiple objects in json file, how can I assign them in an array? e.g.
array[2][0]=*firstName field should be here*
array[2][1]=*lastname field should be here*
Here's a simple push() to build a new array from your JSON:
$.getJSON('https://api.myjson.com/bins/gxs81',function(data){
var current = '';
var myarray = [];
$.each(data.employees,function(i,emp){
current = emp.firstName+' '+emp.lastName;
$('ul').append('<li>'+current+'</li>');
myarray.push(current);
});
});
