How to turn an array into an object with two values? javascript

Question

I want to put an array into an object with two keys (key, val). This is my code.

var arr = ["hello", "44", "thanks", "32"];

console.log(arr);
console.log(arr.length);

var obj = {};

for (var i = 0; i < arr.length; i++) {
    obj.key = arr[i];
}

console.log(obj);

this is the result i would like to have.

obj[0] = {key: "hello", val: "44"}; 
obj[1] = {key: "thanks", val: "32"};

Thanks allot!

So, what you want is a loop every 2 item instead of 1, and then take the current item and the next one.

Maybe something like this :

obj = [];
for (var i = 0; i < arr.length; i=i+2) {
  obj.push({key:arr[i], val:arr[i+1]});
}
