It seems like a basic thing but i am unable to find where i am going wrong .
I want output in this key value format .
[{"10":"bob"},{"20":"Tom"},{"30":"Larry"}]
What i am doing -
var list = [];
var names = ["Bob","Tom","Larry"];
var ages = ["10", "20", "30"];
for(var i=0; i<names.length; i++){
list.push({ages[i] : names[i]})
}
But i am getting unexpected token error . Kindly guide where i am going wrong ?
To set a dynamic string as a property of an object, you can use square bracket notation (obj[propVariable]). So, just store an empty object into a variable (var item = {}), and then you can set its property through item[propVariable].
var list = [];
var names = ["Bob","Tom","Larry"];
var ages = ["10", "20", "30"];
for(var i=0; i<names.length; i++){
var item = {};
item[ages[i]] = names[i];
list.push(item);
}
console.log(list);You can read more about square bracket notation here and here.
To create dynamic properties you need to use bracket notation : Try the following:
var list = [];
var names = ["Bob","Tom","Larry"];
var ages = ["10", "20", "30"];
for(var i=0; i<names.length; i++){
list.push({[ages[i]] : names[i]})
}
console.log(list);
