从包含关键字的对象数组中查找键 - JS

Question

So I have an array of objects that look like this:

 [
  {
    Other: 23,
  },
  {
    Choco: 21,
  },
  {
    Vanila: 10,
  },
  {
    "Other - WA": 2,
  },
  {
    Strawbery: 30,
  },
];

What needs to be done is I have to sort this by showing:

1. All that have keys 'Other'.
2. The rest starting from most to least by value.

I figured I could create 2 separate arrays by moving all that have key 'Other' there and the rest in a separate one. Then I simply sort by value and then join the 2 arrays using spread operator. The problem is I can't get it to detect 'Other' in the key and when it does it does it literally not like how 'LIKE' from SQL would do here's the code for now:

let other = pgData.contents[6]?.locCounts?.filter((loc) =>
  Object.keys(loc).includes("Other")
);

It only returns key with "Other" not "Other - WA" like I want to get everything that has the word "Other" in it regardless of whats in front of it.

Answer 1

includes() on an iterator does an exact match against the elements, not a substring match. Use find() with a callback function that performs a substring match. You can use includes on the key to check for a substring there.

Object.keys(loc).find(key => key.includes("Other"))

If you want to make two arrays, you can do it in a single loop instead of using two calls filter() :

let other = [];
let not_other = [];
pgData.contents[6]?.locCounts?.forEach(loc => {
  if (Object.keys(loc).find(key => key.includes("Other"))) {
    other.push(loc);
  } else {
    not_other.push(loc);
}

Answer 2

I simply modified your code a bit. Here's a one-liner:

 var arr = [{ Other: 23, }, { Choco: 21, }, { Vanila: 10, }, { "Other - WA": 2, }, { Strawbery: 30, }, ] var newArr = arr.filter(el => Object.keys(el)[0].includes("Other")) console.log(newArr)

Answer 3

you could iterate the items and use include on the values like this:

 let arrayOfObj = [ { Other: 23, }, { Choco: 21, }, { Vanila: 10, }, { "Other - WA": 2, }, { Strawbery: 30, }, ]; let results = [] arrayOfObj.forEach( (e)=> { keys = Object.keys(e) others = keys.forEach( (e)=> { if (e.includes('Other')) { results.push(e) } }) }) console.log(results)
