Lodash _.rearg


Lodash is a popular utility library for JavaScript that provides numerous convenient functions that can help developers write cleaner and more efficient code. One of the functions offered by Lodash is the _.rearg method.

The _.rearg method is used to rearrange the arguments passed into a function. It takes two parameters: the function to be rearranged and an array that specifies the order in which the arguments should be rearranged. The function is then returned with the argument list rearranged according to the order specified in the array.

Here is an example of how _.rearg can be used:

const greet = (greeting, name) => `${greeting}, ${name}!`;
const newGreet = _.rearg(greet, [1, 0]);

newGreet('Hello', 'John');

In this example, we define a simple function that takes two arguments, a greeting and a name, and returns a string. We then use _.rearg to create a new function, newGreet, that has the arguments rearranged so that the name argument comes first and the greeting argument comes second. When we call newGreet, we pass in the arguments in the original order, but they are rearranged by the function to produce the expected output: "John, Hello!".

The _.rearg function can be useful when working with functions that have a fixed parameter order, but you need to pass the parameters in a different order. By using _.rearg, you can avoid having to manually rearrange the arguments every time you call the function.

Overall, the _.rearg method is a powerful tool that can help you write more readable and efficient code in JavaScript.
