Explain the differences between the call and bind methods in JavaScript and how they affect the execution context of a function.

The call and bind methods in JavaScript are used to control the context (this) when calling a function, but they work differently:

• call invokes the function immediately, passing the context and arguments. For example:

function greet(greeting) {
  console.log(greeting + ', ' + this.name);
}

const person = { name: 'Ivan' };
greet.call(person, 'Hello'); // Outputs: Hello, Ivan

• bind returns a new function with the bound context, which can be called later:

const boundGreet = greet.bind(person);
boundGreet('Good morning'); // Outputs: Good morning, Ivan

Thus, call executes the function immediately with the specified context, while bind creates a new function with a fixed context for later invocation.
