I'm trying to remove the empty strings in my array.
This is my array:
let array = [{name:'John',age:'18',address:''},{name:'George',age:'',address:''},{name:'Kevin',age:'25',address:''}]
I would like to remove the empty string values ONLY if it's empty in all objects.
desired outcome:
[{name:'John',age:'18'},{name:'George',age:''},{name:'Kevin',age:'25'}]
This is what I did but it removes EVERY empty string values:
for (let i = 0; i < array.length; i++) {
array[i] = Object.fromEntries(Object.entries(array[i]).filter(([_, v]) => v != ''));
}
Thanks in advance ,
If you don't mind mutating the original array object. Here's a solution utilizing some array functions.
let array = [
{ name: 'John', age: '18', address: '' },
{ name: 'George', age: '', address: '' },
{ name: 'Kevin', age: '25', address: '' }
]
Object.keys(array[0])
.filter(k => array.every(obj => !obj[k]))
.forEach(k => array.forEach(obj => delete obj[k]));
console.log(array);You can solve this issue with a filter method
let array = [{name:'John',age:'18',address:''},{name:'George',age:'',address:''},{name:'Kevin',age:'25',address:''}]
const entries = Object.keys(array[0])
entries.forEach(e => {
if(array.filter(i => i[e]).length === 0) {
array = array.map(i => {delete i[e]; return i})
}
})
console.log(array)If you don't want to mutate the original array:
let array = [{name:'John',age:'18',address:''},{name:'George',age:'',address:''},{name:'Kevin',age:'25',address:''}]
let result;
Object.keys(array[0])
.forEach(key => {
if(array.every(e => e[key] === ''))
result = array.map(({[key]:_,...rest}) => ({...rest}))
})
console.log(result)
