Lodash - invokeMap method

Syntax

_.invokeMap(collection, path, [args])

Invokes the method at path of each element in collection, returning an array of the results of each invoked method. Any additional arguments are provided to each invoked method. If path is a function, it's invoked for, and this bound to, each element in collection.

Arguments

• collection (Array|Object) − The collection to iterate over.

• path (Array|Function|string) − The path of the method to invoke or the function invoked per iteration.

• [args] (...*) − The arguments to invoke each method with.

Output

• (Array) − Returns the array of results.

Example

var _ = require('lodash');
var list = [[5, 1, 7], [3, 2, 1]];
 
var result = _.invokeMap(list, 'sort');
console.log(result);

result = _.invokeMap([123, 456], String.prototype.split, '');
console.log(result);
