I want to remove 3rd object from an array in which the color is red. I want to remove it using the index as some objects may not have an _id attribute and other attributes are not unique among them.
[
{ color: "BLUE"
imageURL: "/uploads/image-1639632524718.png"
inStock: 4
_id: "61b9bff23b027548ed2f737e"
},
{ color: "green"
imageURL: "/uploads/image-1639561204805.png"
inStock: 6
_id: "61ba098f3b027548ed2f737f"
},
{ color: "Red"
imageURL: "/uploads/image-1639647424471.png"
inStock: 6
},
{ color: "Star Light"
imageURL: "/uploads/image-1639650244179.png"
inStock: 60
}
]
After removing the object array will look like.
[
{ color: "BLUE"
imageURL: "/uploads/image-1639632524718.png"
inStock: 4
_id: "61b9bff23b027548ed2f737e"
},
{ color: "green"
imageURL: "/uploads/image-1639561204805.png"
inStock: 6
_id: "61ba098f3b027548ed2f737f"
},
{ color: "Star Light"
imageURL: "/uploads/image-1639650244179.png"
inStock: 60
}
]
How can I do this?
this splice function does that
someArray.splice(index, 1)
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/splice
Use Array.splice() method to remove item from specified position.
const list = [
{ color: "BLUE",
imageURL: "/uploads/image-1639632524718.png",
inStock: 4,
_id: "61b9bff23b027548ed2f737e"
},
{ color: "green",
imageURL: "/uploads/image-1639561204805.png",
inStock: 6,
_id: "61ba098f3b027548ed2f737f"
},
{ color: "Red",
imageURL: "/uploads/image-1639647424471.png",
inStock: 6
},
{ color: "Star Light",
imageURL: "/uploads/image-1639650244179.png",
inStock: 60
}
];
const remove = (arr, index) => arr.splice(index, 1);
remove(list, 2);
console.log("list after removal: ", list);(Once you've fixed your data structure - it's not an array, and you're missing commas...)
You can filter out all those objects that aren't located at that index.
const data=[{color:"BLUE",imageURL:"/uploads/image-1639632524718.png",inStock:4,_id:"61b9bff23b027548ed2f737e"},{color:"green",imageURL:"/uploads/image-1639561204805.png",inStock:6,_id:"61ba098f3b027548ed2f737f"},{color:"Red",imageURL:"/uploads/image-1639647424471.png",inStock:6},{color:"Star Light",imageURL:"/uploads/image-1639650244179.png",inStock:60}];
const out = data.filter((obj, i) => i !== 2);
console.log(out);
