How can I use lodash trim method to trim both key and value.

    "Id": 11,
    "name": "xxN"

Answer 1

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]))

Answer 2

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)

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);

Answer 4

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
  ])
);
