Lodash _.invokeMap() Method

Lodash_.invokeMap() method invokes the method at the given path of each element in the collection and returns an array of the results of each invoked method. Additional arguments can be provided for each invoked method using the args parameter. The given path can also be a function that would be bound to each element in the collection.

Syntax:

_.invokeMap( collection, path, args );

Parameters:

• collection: This parameter holds the collection that has to be iterated over.
• path: This parameter holds the path of the method to invoke or the function invoked per iteration.
• args: This parameter holds the arguments to invoke each method with.

Return Value:

This method returns the array of results.

Example 1: In this example, we are sorting the given array by the use of the lodash _.invokeMap() method.

javascript

// Requiring the lodash library
const _ = require('lodash');

// Original array
let obj = [[6, 2, 8], [2, 1, 0]];

// Using the _.invokeMap() method
let gfg1 = _.invokeMap(obj, 'sort');

// Printing the output
console.log(gfg1);

Output:

[ [ 2, 6, 8], [ 0, 1, 2 ] ]

Example 2: In this example, we are spliting the given array by the use of the lodash _.invokeMap() method.

javascript

// Requiring the lodash library
const _ = require('lodash');

// Original array
let obj = [628, 210];

// Using the _.invokeMap() method
let gfg1 = _.invokeMap(obj, String.prototype.split, '');

// Printing the output
console.log(gfg1);

Output:

[ [ '6', '2', '8'], [ '2', '1', '0' ] ]

Example 3: In this example, we are spliting the given array by the use of the lodash _.invokeMap() method.

javascript

// Requiring the lodash library
const _ = require('lodash');

// Original array
let obj = ['srqp', 'tuvw'];
let obj1 = [['c', 'b', 'a'], ['f', 'e', 'd']];

// Using the _.invokeMap() method
let gfg = _.invokeMap(obj, String.prototype.split, '');
let gfg1 = _.invokeMap(obj1, 'sort');

// Printing the output
console.log(gfg, gfg1);

Output:

[ [ 's', 'r', 'q', 'p'], [ 't', 'u', 'v', 'w' ] ]
[ [ 'a', 'b', 'c'], [ 'd', 'e', 'f' ] ]
