Generating an array of objects with various attributes in JavaScript

Question

Generating an array of objects with various attributes in JavaScript

Is there a way to efficiently create an array of objects with properties for "name" and "shade"?

[{
    "name": "black",
    "shade": "dark"
  }, {
    "name": "white",
    "shade": "light"
  },
  {
    "name": "red",
    "shade": "dark"
  }, {
    "name": "blue",
    "shade": "dark"
  },
  {
    "name": "yellow",
    "shade": "light"
  }]

Currently, I have two separate arrays:

name = ["black","white","red","blue","yellow"]
shade = ["dark","light","dark","dark","light"]

What are the steps needed to combine these arrays into one cohesive object array structure?

Answer 1

Answer №1

Utilize the map function.

let result = names.map( (name, index) => ({ name: name, color: colors[index] }) );

Example

const names = ["black","white","red","blue","yellow"];

const colors = ["dark","light","dark","dark","light"];

let result = names.map( (name, index) => ({ name: name, color: colors[index] }) );

console.log(result);

Answer 2

Utilize the map function.

let result = names.map( (name, index) => ({ name: name, color: colors[index] }) );

Example

const names = ["black","white","red","blue","yellow"];

const colors = ["dark","light","dark","dark","light"];

let result = names.map( (name, index) => ({ name: name, color: colors[index] }) );

console.log(result);

let combined_arrays = [];
// ensuring the arrays are of equal length
for (let j = 0; j < colors.length; j++)
    combined_arrays.push({color: colors[j], tone: tones[j]});

let combined_arrays = [];
// ensuring the arrays are of equal length
for (let j = 0; j < colors.length; j++)
    combined_arrays.push({color: colors[j], tone: tones[j]});

You could utilize the .map() method for this task:

let colors = ["green", "purple", "orange", "pink", "turquoise"],
    tones = ["deep", "pastel", "vibrant", "soft", "bright"];

let combine = (arr1, arr2) => colors.map((color, index) => ({color: color, tone: tones[index]}));

console.log(combine(colors, tones));

.as-console-wrapper { max-height: 100% !important; top: 0; }

One way to simplify handling various types is by using a helper object.

var colors = [ "red", "green", "blue", "yellow"],
    shades = ["dark", "light", "dark", "dark", "light"],
    data = { color: colors, shade: shades },
    processedData = Object
        .keys(data)
        .reduce(
            (result, key) => (data[key].forEach((value, index) => (result[index] = result[index] || {})[key] = value), result),
            []
        );

console.log(processedData);

.as-console-wrapper { max-height: 100% !important; top: 0; }
