lodash map and pick

Question

given an array

var test = [{a:1, b:2, c:3}, {a:4, b:5, c:6}, {a:7, b:8, c:9}]

how do I get an array of new objects like [{b:2, c:3}, {b:5, c:6}, {b:8, c:9}] with lodash?

I have tried _.map(test, _pick(???, ['b', 'c'])} What should I put in ??? ?

Answer 1

You need to pass function to map and with ES6 you can use arrow function like this.

var test = [{a:1, b:2, c:3}, {a:4, b:5, c:6}, {a:7, b:8, c:9}]

var result = _.map(test, e => _.pick(e, ['b', 'c']))
console.log(result)
