Combine array of string and number as object array conditionally

Question

I have two array, one is type of String and second one is number. How can I combine these conditionally as key value objects.

For example:

var fruits = [
  "Apple",
  "Banana" ,
  "Apricot",
  "Bilberry"
]

var count = [3,5,0,2]

I want to combine fruits and count array as key value object and which count is not 0

Expected:

var merge = [{"Apple":3},{"Banana" :5},{"Bilberry":2}]

What i have tried is:

var merge = _.zipObject(["Apple","Banana" ,"Apricot","Bilberry"], [3,5,0,2])

and result is:

{"Apple":3,"Banana":5 ,"Apricot":0,"Bilberry":2}

Try this vanilla js solution as well using filter, Object.values and map

var output = count.map((s, i) => ({
  [fruits[i]]: s
})).filter(s => Object.values(s)[0]);

Demo

var fruits = [
  "Apple",
  "Banana",
  "Apricot",
  "Bilberry"
];

var count = [3, 5, 0, 2];

var output = count.map((s, i) => ({
  [fruits[i]]: s
})).filter(s => Object.values(s)[0]);

console.log(output);
