Assigning 2 arrays key value in Javascript?

Question

I have two arrays

ar1 = ["jhon", "doe", "alex"];
ar2 = ["21", "22", "35"];

I want to convert them into an object just like following

obj=[
{name:'jhon',age:'21'},
{name:'doe', age:'22'},
{name:'alex', age:'35'}
]

how do I that in javascript?

You can use the map function:

var arr1 = ["jhon", "doe", "alex"];;
var arr2 = ["21", "22", "35"];

const obj = arr1.map((item, index) => {
  return {
   name: item,
   age: arr2[index]
  }
})

On the map function, just to clean the code, you can use an implicit return:

const obj = arr1.map((item, index) => ({
  name: item,
  age: arr2[index]
 })
)
