From a string which looks like:
"Apple Banana 26"
or
"Dog Likes Food"
How would one get objects such as:
Apple={Banana:"26"}
Dog={Likes:"Food"}

Assuming you want an object not a variables from strings (which gets ugly) you can simply reduceRight()
let str = "Dog Likes Food"
let obj = str.split(' ').reduceRight((obj, word) => ({[word]: obj}))
console.log(obj)This has the added benefit that it doesn't care how many words you have:
let str = "Dog Likes To Eat Dog Food"
let obj = str.split(' ').reduceRight((obj, word) => ({[word]: obj}))
console.log(obj)If you are determined to get the variable Dog you can use Object.assign to merge the object with the window object creating a global. But there's almost always a better approach than creating globals:
let str = "Dog Likes Food"
let obj = str.split(' ').reduceRight((obj, word) => ({[word]: obj}))
Object.assign(window, obj)
console.log(Dog)

You can try to convert the 3-words string to a JSON object, I show you the idea in the next example:
var string1 = "Apple Banana 26";
var string2 = "Dog Likes Food";
// Convert 3 words string to a JSON object.
function strToObj(str)
{
var items = str.split(' ');
if (items.length != 3)
return false;
var jsonStr = '{"' + items[0] + '":' +
'{"' + items[1] + '":"' +
items[2] + '"}}';
return JSON.parse(jsonStr);
}
// Test the method.
var apple = strToObj(string1);
if (apple)
console.log(apple);
else
console.log("Fail to convert!");
var dog = strToObj(string2);
if (dog)
console.log(dog);
else
console.log("Fail to convert!");
