Arrays:
*Merge two array as key value pair
Merge two array as key value pair
suggest changeWhen we have two separate array and we want to make key value pair from that two array, we can use array’s reduce function like below:
var columns = ["Date", "Number", "Size", "Location", "Age"];
var rows = ["2001", "5", "Big", "Sydney", "25"];
var result = rows.reduce(function(result, field, index) {
result[columns[index]] = field;
return result;
}, {})
console.log(result);Output:
{
Date: "2001",
Number: "5",
Size: "Big",
Location: "Sydney",
Age: "25"
}
