Insert object on array in key value format

Question

I have an object set like this

var total = { \'Apple\': 0.6,
              \'Banana\': 0.6,
              \'Orange\': 1,
              \'Grapes\': 0.4,
             


        

Answer 1

Array#reduce can also be used to "Insert object on array in key value format":

var total = { 'Apple': 0.6, 'Banana': 0.6, 'Orange': 1, 'Grapes': 0.4, 'Pineapple': 0.4 };

var objArr = Object.entries(total)
                   .reduce((accumulator, [name, value]) => {
                      return accumulator.concat({name: name, value: value});  // creates an array of objects
                     }, [])
                   .sort((a, b) => b.value - a.value);  // sorting in descending order

console.log(objArr);

For more info read Object#entries, Array#sort and object destructuring.

Answer 2

 const result = Object.entries(total).map(([name, value]) => ({name, value}));

Answer 3

You can use Array#map function on the object keys and create your objects with desired shape.

const total = { 
    'Apple': 0.6,
    'Banana': 0.6,
    'Orange': 1,
    'Grapes': 0.4,
    'Pineapple': 0.4 
};
              
const array = Object.keys(total)
                    .map(key => ({ name: key, value: total[key] }))
                    .sort((f, s) => f.value - s.value);

console.log(array);

If you use ES7 or higher you can replace Object#keys with Object#entries. Use also object destructuring in the parameter list to get name and value separately.

const total = { 
    'Apple': 0.6,
    'Banana': 0.6,
    'Orange': 1,
    'Grapes': 0.4,
    'Pineapple': 0.4 
};
              
const array = Object.entries(total)
                    .map(([name, value]) => ({ name, value }))
                    .sort((f, s) => f.value - s.value);;

console.log(array);
