Lodash Filter Matching For Multiple Values In Nested Objects

I have an array of objects const obj = [ { 'id': 20000, 'attributes': [ { 'name': 'Size', 'value': '38'

Solution 1:

Without a library, you could directly use Array#filter to obtain only specific elements.

Object.entries can be used to get the key-value pairs of the selected attributes, Array#every can be used to ensure that all entries match a given condition, and Array#some can be used to check that the key and value exist in the attributes array of the object.

const obj=[{id:2000,attributes:[{name:"Size",value:"38"},{name:"Color",value:"Blue"}]},{id:20056,attributes:[{name:"Size",value:"38"},{name:"Color",value:"Brown"}]}];
const selectedAttributes = {
    "Color": "Brown",
    "Size": "38"
}
const selectedAttributes2 = {
    "Size": "38"
}
constmatches = (arr, attrs)=>arr.filter(x =>Object.entries(attrs).every(([k, v])=>
    x.attributes.some(a => a.name === k && a.value === v
)));
console.log(matches(obj, selectedAttributes));
console.log(matches(obj, selectedAttributes2));
