javascript中两个数组合并形成新的键值对数组

Question

Array a=['india','germany','russia'];
Array b=[100,70,60];
Array c =[
{Country:"india", val:100},
{Country:"germany", val:70},
{Country:"russia", val:60},];

i want the result array like Array c.

Answer 1

a=['india','germany','russia'];
b=[100,70,60];
const c=[]
for(var i=0;i<a.length;i++){
data={
"Country":a[i],
"val":b[i]
}
c.push(data)
}
console.log(c)

Answer 2

let a=['india','germany','russia'];
let b=[100,70,60];
let c=a.map((country,index)=>{
    return {
        "Country":country,
        "val":b[index]
    };
});

This code loops through the first array, (In case the number of elements are different for both arrays, use the array with smallest length or use default value) and sets the value of the array as the object with those properties.

Answer 3

 let a=['india','germany','russia']; let b=[100,70,60]; let c = []; for(let i in a) { c.push({country: a[i], val: b[i]}); } console.log(c);
