Is there a way to remove the property 'b' from all objects in an array?
let result=[
{
'id':'1',
'b':'asd'
},
{
'id':'2',
'b':'asd'
},
...
,
{
'id':'2000',
'b':'asd'
},
]
// Is it possible to delete object.b from the entire array of 2000 records?
Would using a foreach loop be the correct approach to deleting a key + value pair from an array of objects?
When dealing with just one structure, you have the option to execute the following:
result = result.map(e => ({ id: e.id }))
If the structure is more complex, consider using the delete method like so:
result.forEach((e) => {
delete e.b;
});
You may consider using the forEach method.
let data=[
{
'id':'1',
'b':'abc'
},
{
'id':'2',
'b':'def'
},
{
'id':'2000',
'b':'ghi'
},
];
data.forEach(function(entry){ delete entry.b });
console.log(data);Take a look at the following code snippet:
let data=[
{
'id':'10',
'name':'John'
},
{
'id':'20',
'name':'Jane'
},
];
for(let j in data){
let item = data[j];
delete item['name'];
}
console.log(data);I hope this code proves to be helpful :)
