The _.zipObject() method is used to combine two arrays into an object one array as keys and the other as values.
Syntax:
_.zipObject([props=[]], [values=[]])
Parameters: This method accepts two parameters as mentioned above and described below:
- [props=[]](array): This parameter holds the property identifiers.
- [values=[]](array): This parameter holds the property values.
Return Value: This method returns an object containing key values corresponding to the given array.
Example 1:
Javascript
const _ = require('lodash'); let x = ['a', 'b', 'c']; let y = [1, 2, 3] let obj = _.zipObject(x, y) console.log(obj); |
Here, const _ = require(‘lodash’) is used to import the lodash library into the file.
Output:
{ a: 1, b: 2, c: 3 }
Example 2:
Javascript
const _ = require('lodash'); let x = ['name', ';language', 'used']; let y = ['lodash', 'JavaScript', 'nodejs'] let obj = _.zipObject(x, y) console.log(obj); |
Output:
{ name: 'lodash', ';language': 'JavaScript', used: 'nodejs' }
Example 3: If you pass an extra key and no values for it, it will put undefined value associated with that key.
Javascript
const _ = require('lodash'); let x = ['a', 'b', 'c', 'd']; let y = [1, 2, 3] let obj = _.zipObject(x, y) console.log(obj); |
Output:
{ a: 1, b: 2, c: 3, d: undefined }
Example 4: If you pass an extra value and no key for it, it will ignore that value.
Javascript
const _ = require('lodash'); let x = ['a', 'b', 'c']; let y = [1, 2, 3, 4] let obj = _.zipObject(x, y) console.log(obj); |
Output:
{ a: 1, b: 2, c: 3 }
Note: This will not work in normal JavaScript because it requires the library lodash to be installed.
