What dependencies do you already have, and what is your team already comfortable with? Take note: There is a much more specific method for this use-case: _.pluck. One of the most useful feature when you work with collections, is the shorthand syntax: import * as _ from "lodash"; const array = [1, 2, 3]; const result = _.indexOf(array, 2, 1); console.log(result); Then we get 1 since 2 is in the 2nd position and we search from the start. Never the less when dealing with simple arrays, it is pretty safe to just use that method to get the index, as a solution with _.findIndex will be overly complex by comparison. At work, we are using lodash in our front end applications. - codemix/fast.js There are however other methods of interest, both in lodash and native javaScript though such as the filter method that might be a better option as it will do the same only not mutate the array in place.

Lodash is available in a variety of builds & module formats. Further Reading. Further Reading. We can see that Lodash performs 45% slower than using the native code. value (*): The value to search for. In many cases I also find the code is more readable. Lodash is a well-known JavaScript utility library that makes it easy to manipulate arrays and objects, as well as functions, strings, etc. We therefore avoid the question, “Can we use the native function in this case?” and we avoid multiple implementations of the same solution by always deferring to the Lodash API. indexOf - Returns the index of the first occurrence of a value in an array. Lodash is inspired by Underscore.js, but nowadays it is a superior solution. Filtering on an array of integers shows no significant difference, in terms of performance, between vanilla and lodash. Jeremy Ashkenas (also known for Backbone & Coffeescript) ~ 130 methods ~ 2M downloads per week; lodash.com.

The Lodash indexOf method is the same as the plain JavaScript’s indexOf method. The lo-dash developers explain that the relative speed of the native forEachvaries among browsers.Just because forEach is native does not mean that it is faster than a simple loop built with for or while.For one thing, the forEach has to deal with more special cases.
