My array is of multiple objects
[
{ key: 'javascript', count: 12 },
{ key: 'typescript', count: 15 },
{ key: 'angular', count: 13 }
]
How can I push inside each object to make it like
[
{ key: 'javascript', count: 12, selected: false },
{ key: 'typescript', count: 15, selected: false },
{ key: 'angular', count: 13, selected: false }
]
let t = [
{ key: 'javascript', count: 12 },
{ key: 'typescript', count: 15 },
{ key: 'angular', count: 13 }
];
t.forEach(myObj => (myObj.selected = false));
console.log(t);After author commented:
let t = {
0:[ { key: 'javascript', count: 12 }, { key: 'typescript', count: 15 }, { key: 'angular', count: 13 } ],
99:[ { key: 'javascript', count: 12 }, { key: 'typescript', count: 15 }, { key: 'angular', count: 13 } ],
};
Object.keys(t).forEach(myNum =>
t[myNum].forEach(myObj => myObj.selected = false));
console.log(t);
let t = { 0:[ { key: 'javascript', count: 12 }, { key: 'typescript', count: 15 }, { key: 'angular', count: 13 } ], 99:[ { key: 'javascript', count: 12 }, { key: 'typescript', count: 15 }, { key: 'angular', count: 13 } ], }; Object.keys(t).forEach(myNum => t[myNum].forEach(myObj => myObj.selected = false)); console.log(t); You could use Array#Map
var items = [
{key:"javascript" , count : 12},
{key:"typescript", count: 15},
{key:"angular" , count: 13}
]
console.log(items.map(item=>({...item, selected: false})))
const data = [
[
{ key: 'javascript', count: 12 },
{ key: 'typescript', count: 15 },
{ key: 'angular', count: 13 }
]
];
data[0].forEach(item => (item.selected = false));
console.log(data);
