I have a dictionary structure as follows :
data = { a : [5, 10], b : [1, 12] , c : [6, 7]}
I need to convert this to follows :
[ a, 5, 10 ], [ b, 1, 12 ], [ c, 6, 7 ]
I've already tried using Object.entries(data), but it returned the data like : [a, [5, 10]], [b, [1, 12]]
How can i do this using JavaScript?
You could map the key/values in a new array.
var data = { a : [5, 10], b : [1, 12] , c : [6, 7]},
result = Object.entries(data).map(([k, v]) => [k, ...v]);
console.log(result);Another way:
const data = { a : [5, 10], b : [1, 12] , c : [6, 7]};
const result = Object.entries(data).map(pair => pair.flat());
console.log(result);So with Object.keys() and reduce() you can solve as the following:
const data = { a: [5, 10], b: [1, 12], c: [6, 7] };
const result = Object.keys(data).map(e => {
return data[e].reduce((a, c) => {
a.push(c);
return a;
}, Array.from(e));
});
console.log(result);I hope that helps!
var dict = { 'a': 'aa', 'b': 'bb' };
var arr = [];
for (var key in dict) {
if (dict.hasOwnProperty(key)) {
arr.push( [ key, dict[key] ] );
}
}
this might helps you out
