Efficiently eliminating one array from another in JavaScript with just a single line of code

In my angular application, I have two arrays - products and productsGreen. The products array contains all products, while the productsGreen array only has successful products.

When the user deselects the green checkbox, I want to remove productsGreen from products. Most solutions involve using loops and multiple lines of code.

Is there a way to achieve this in just one line of code, like products.remove(productsGreen)?

Here is the products array:

{
    "color": "green",
    "loc": "L1"
},
{
    "color": "green",
    "loc": "L2"
},
{
    "color": "red",
    "loc": "L5"
},
{
    "color": "red",
    "loc": "L6"
},

And here is the productsGreen array:

{
    "color": "green",
    "loc": "L1"
},
{
    "color": "green",
    "loc": "L2"
},

The desired output should be:

{
    "color": "red",
    "loc": "L5"
},
{
    "color": "red",
    "loc": "L6"
},

Edit 1:

Below is the code snippet:

OnChangeGreen($event)
{
if(this.CheckboxGreen==true)
{
  this.CheckboxGreen=false;
  this.chartData.pop(this.mapDatagreen)  
  this.mapImageSeries.data=this.chartData;
  this.chartData.validateData();
}
}

If you want to filter an array of objects based on their properties, you can follow this simple concept:

var data = [{
    "color": "green",
    "loc": "L1"
  },
  {
    "color": "green",
    "loc": "L2"
  },
  {
    "color": "red",
    "loc": "L5"
  },
  {
    "color": "red",
    "loc": "L6"
  }
];

const selectItems = filters =>
  data.filter(item => filters.includes(item.color))


console.log("red", selectItems(["red"]));
console.log("green", selectItems(["green"]));
console.log("red green", selectItems(["red", "green"]));
console.log("blue", selectItems(["blue"]));
