I need help with removing arrays that have a value of 0 in an object.
For example:
dynamic:{"FIRST":[ 0, 0 ,0 ,0], "TEST": [1, 12,123, 12], "KING": [0 , 0 ,0 ,0], "NEXT": [2, 3,4,55]}Expected outcome:- dynamic:{ "TEST": [1, 12,123, 12], "NEXT": [2, 3,4,55] }Object.entries to transform an object into an array,every if all elements are 0, or some if any element is 0)Object.fromEntriesconst transformation = (object) =>
Object.fromEntries(
Object.entries(object).filter(([, arr]) => !arr.every((element) => element === 0))
);
dynamicData = {
FIRST: [0, 0, 0, 0],
TEST: [1, 12, 123, 12],
KING: [0, 0, 0, 0],
NEXT: [2, 3, 4, 55],
};
console.log(transformation(dynamicData));To efficiently check and remove empty arrays within an object, you can utilize the Array.prototype.every() method:
const data = {
dynamic: {
"FIRST": [0, 0, 0, 0],
"TEST": [1, 12, 123, 12],
"KING": [0, 0, 0, 0],
"NEXT": [2, 3, 4, 55]
}
}
Object.keys(data['dynamic']).forEach(key => {
if (data['dynamic'][key].every(item => item === 0)) {
delete data['dynamic'][key];
}
});
console.log(data);Obtain the key and then inspect the values in this manner
const dynamic = {
"FIRST": [0, 0, 0, 0],
"TEST": [1, 12, 123, 12],
"KING": [0, 0, 0, 0],
"NEXT": [2, 3, 4, 55]
}
const result = Object.keys(dynamic).reduce((acc, key) => {
const val = dynamic[key];
if (val.some(v => v !== 0)) {
acc[key] = val;
}
return acc;
}, {});
console.log(result);I'm currently working on incorporating a new object into an array that I'm fetching dynamically through my API. Users fill out a form, and the data is transmitted from the form to the state. The initial fetch stores the original array in a React ...
