How does lodash.spread work?

lodash.spread is a function in the Lodash library that takes a function with multiple arguments and returns a new function that can spread an array of arguments into the original function. Here's how it works:

You start by passing a function with multiple arguments to lodash.spread, which returns a new function that can be called with an array of arguments.
When you call the new function with an array of arguments, lodash.spread will use the apply method to spread the array of arguments into the original function.
The original function is called with the individual elements of the array as separate arguments.
The result of the original function call is returned as the result of the new function.

Here is an example of using lodash.spread:

javascript
const spreadFn = lodash.spread((a, b, c) => a + b + c);

console.log(spreadFn([1, 2, 3])); // Output: 6

In this example, we create a new function using lodash.spread that takes three arguments and returns their sum.

We then call the new function with an array of three numbers, which is spread into the original function using apply.

The original function adds up the three numbers and returns their sum, which is logged to the console.

Note that the lodash.spread function is often used in conjunction with other Lodash functions like _.map or _.reduce, which allow you to process arrays of values with a function that expects multiple arguments. By using lodash.spread, you can write these functions as if they take individual arguments, but still handle arrays of values as input.

var say1 = say('hello', 'fred', 'barney', 'pebbles');
console.log('say1--->', say1);
//say1---> hello fred, barney, & pebbles


//_.spread(func,[start=0])
var spreadSay = _.spread(function (who, what) {
    return who + ' says ' + what;
});
var spreadSay1 = say(['fred', 'hello']);
console.log('spreadSay1--->', spreadSay1);

const lodash = require("lodash");

function sum(a, b, c) {
  return a + b + c;
}

const spreadFn = lodash.spread(sum);

console.log(spreadFn([1, 2, 3])); // Output: 6

In this example, we define a function sum that takes three arguments and returns their sum. We then create a new function using lodash.spread and pass sum as the argument. This creates a new function that can accept an array of values as its argument, which is then spread into sum. Finally, we call the new function with an array of three numbers [1, 2, 3], and it returns the sum of those numbers, which is 6. Note that we could also have achieved the same result without using lodash.spread like this: javascript Copy code
