Filter Object by it's values

i'm trying to filter an array of objects based on them objects having a value which partially matches a string.

const acceptedValues = "theme";
const myObject = {
  code: "themev3",
}

var filteredObject = Object.keys(myObject).reduce(function(r, e) {
  if (acceptedValues.indexOf(myObject[e].toLowerCase()) >= 0) r[e] = myObject[e]
  return r;
}, {})

console.log(filteredObject);

As you can see the object above should be returned in the filteredObject array as code has got theme in it.

This is not working however, any ideas why?

Beside the switching comparison, you could map the key/value pairs and build new objects after filtering.

const
    value = "theme",
    object = { code: "themev3" },
    filtered = Object.assign(
        ...Object
            .entries(object)
            .filter(([, v]) => v.toLowerCase().includes(value))
            .map(([key, value]) => ({ [key]: value }))
    );

console.log(filtered);

The condition should be reverse. You need to find the index of acceptedValues in the object values instead:

const acceptedValues = "theme";

const myObject = {
  code: "themev3",
}

var filteredObject = Object.keys(myObject).reduce(function(r, e) {
  if (myObject[e].toLowerCase().indexOf(acceptedValues.toLowerCase()) > -1)
    r[e] = myObject[e];
    
  return r;
}, {})

console.log(filteredObject);

You are mixing up the searched text and search from text. Over here you need to check whether myObject[e] has any part of the acceptedValues

const acceptedValues = "theme";
const myObject = {
  code: "themev3",
}

var filteredObject = Object.keys(myObject).reduce(function(r, e) {
  if (myObject[e].toLowerCase().indexOf(acceptedValues) >= 0) r[e] = myObject[e]
  return r;
}, {})

console.log(filteredObject);

Also, you can use includes in place of indexOf like following

if(myObject[e].toLowerCase().includes(acceptedValues))
