I have an array of objects like below.
{
"Id": 11,
"name ": "xxN "
}
How can I use lodash trim method to trim both key and value.
{
"Id": 11,
"name": "xxN"
}
Expected:

Does it have to use Lodash? With vanilla JavaScript:
result = Object.fromEntries(Object.entries(data).map(([key, value]) =>
[key.trim(), typeof value == 'string' ? value.trim() : value]))

looks promising. But I am using node 10 for my project and getting
TypeError: Object.fromEntries is not a function, this error
Spectric
@Nick Node 10 does not support
Object.fromEntries. You have to upgrade to Node 14.Nick
Yes @Spectric, Thats why I was looking for lodash. Can't upgrade the project to node 14. few things might break. 😔

@Spectric I assume he can't upgrade at all.
For completeness, here's a Lodash solution using _.transform()
const obj = {
"Id": 11,
"name ": "xxN "
}
const transformed = _.transform(obj, (result, value, key) => {
result[key.trim()] = typeof value === "string" ? value.trim() : value
})
console.log(transformed)<script src="https://cdn.jsdelivr.net/npm/[email protected]/lodash.min.js"></script>This has the added bonus of producing a new object with the same prototype as your original which may or may not be handy.

Using lodash trim method
const arr = [
{
Id: 11,
"name ": "xxN ",
},
{
Id: 12,
"name ": " yyK ",
},
];
const result = arr.map((o) =>
Object.fromEntries(
Object.entries(o).map(([k, v]) => [k, typeof v === "string" ? _.trim(v) : v])
)
);
console.log(result);<script src="https://cdn.jsdelivr.net/npm/[email protected]/lodash.min.js"></script>

Vanilla js would be better if you had the support for it but with lodash
var trimmed = _.fromPairs(
_.map(input, (value, key) => [
_.trim(key),
typeof value === "string" ? _.trim(value) : value
])
);

Do you need
_.toPairs? Doesn't _.map() work with objects?

@Barmar Good call
