I am trying to create a function that creates groups and allocates a quantity per group, depending on the user input.
For example:
// Input
User input: 150
// Rule
Maximum quantity per group: 100
// Created groups
Group 1: { quantity: 100 }
Group 2: { quantity: 50 }
Goal
This is my desired outcome:
[{ quantity: 100 }, { quantity: 50 }]
What I have tried
function group(input, maximum) {
let arr = (new Array(Math.floor(input / maximum))).fill(maximum);
input % maximum && arr.push(input % maximum);
console.log(arr);
}
group(150, 100);Output
This will return me: [100, 50].
Now I tried implementing this to output me an object:
function group(input, maximum) {
let arr = (new Array({quantity: Math.floor(input / maximum)})).fill(maximum);
input % maximum && arr.push({quantity: input % maximum});
console.log(arr);
}
group(150, 100);Output
This returns me: [100, { "quantity": 50 }].
quantity is only added to the second element, but not the first.
Question
How can I fix this, so all the array elements is an object?
As noted in the comment, the question is very close to the desired objective.
Here's one possible way to achieve the desired target structure.
function group(input, maximum) {
let arr = (new Array(Math.floor(input / maximum))).fill(maximum);
input % maximum && arr.push(input % maximum);
// instead of using "arr", simply transform it
// by putting the number as an object with prop-name "quantity"
console.log(arr.map(quantity => ({ quantity })));
}
group(150, 100);Explanation added as inline comments in the above snippet.
