## README

# function.apply-x

Robustly caches `Function.prototype.apply` for reliable usage across environments.

## Installation

```bash
npm install function.apply-x
```

## Usage

```javascript
const apply = require('function.apply-x');

function greet(greeting, name) {
  return `${greeting}, ${name}!`;
}

// Use apply to call the function with an array of arguments
const result = apply.call(greet, null, ['Hello', 'World']);
console.log(result); // "Hello, World!"
```

## Why?

This module caches a reference to the native `Function.prototype.apply` method. This is useful in scenarios where:

- You need to ensure you're using the original, unmodified `apply` method
- Third-party code may have modified or overridden `Function.prototype.apply`
- You want to protect against prototype pollution
- You're building low-level utility libraries that need guaranteed native behavior

## API

The module exports the cached `Function.prototype.apply` method directly.

```javascript
apply.call(func, thisArg, argsArray)
```

- **func**: The function to invoke
- **thisArg**: The value to use as `this` when calling the function
- **argsArray**: An array of arguments to pass to the function

## Example

```javascript
const apply = require('function.apply-x');

const obj = {
  value: 42,
  getValue: function(multiplier, offset) {
    return this.value * multiplier + offset;
  }
};

const result = apply.call(obj.getValue, obj, [2, 10]);
console.log(result); // 94
```
