Question, I have this array object, I want to find out which of this array have a similar values then make them as one.
Example
[0:
cartProduct: {
category: "chair"
color: "navy"
id: "628a1738fd8299ae6659d994"
image: "http://localhost:5000/../public/Product_chair_communal-navy.jpg"
name: "The Communal"
price: "4.30"
}
quantity: 1,
1:
cartProduct: {{
category: "chair"
color: "navy"
id: "628a1738fd8299ae6659d994"
image: "http://localhost:5000/../public/Product_chair_communal-navy.jpg"
name: "The Communal"
price: "4.30"
}
quantity: 1,
] For example the data above I want to know if they have the similar values interms of color if yes then only return one value.
Thanks!
You can use this loop:
let uniqueArray = [];
dataArray.forEach((item, indx) => {
let colorsArray = [];
if (colorsArray.includes(item.color)) {
continue;
}
uniqueArray.push(item);
})Not the cleanest, or most performant approach:
// function to group the items
const groupCartItems = (items, byProperties = ['color', 'id']) => {
// utility funciton
const verifyEquality = (itemA, itemB) => {
let isEqual = true;
byProperties.forEach((prop) => {
if (itemA.cartProduct[prop] != itemB.cartProduct[prop]) {
isEqual = false;
break;
}
});
return isEqual;
};
const groupedItems = [];
items.forEach((item) => {
// if item has been added, skip
if (groupedItems.find((i) => verifyEquality(item, i))) {
return;
}
// find equal items
const equals = items.filter((i) => verifyEquality(item, i));
// sum quantities
const quantity = equals.reduce((previousValue, data) => previousValue + data.quantity, 0);
// push
groupedItems.push({
cartProduct: item.cartProduct,
quantity,
});
});
return groupedItems;
};
For the 'similarity' stuff, I would recommend not to do this, because it is just not a good practise. Have your values equal or else!!!
Now seriously, check string-similarity. From documentation, you would only need to change the if inside verifyEquality function to:
import stringSimilarity from 'string-similarity';
// tweak this value to change how similar strings should be to be considered equal
const EQUALITY_RATIO = 0.75;
// ....
if (stringSimilarity.compareTwoStrings(itemA.cartProduct[prop], itemB.cartProduct[prop]) < EQUALITY_RATIO) {
}
