Lambdas in golang

Go is a statically-typed programming language that supports lambda functions, also known as anonymous functions. Lambdas in Go are defined using the func keyword, followed by the function parameters and the function body.

Here are the steps to define and use lambdas in Go:

1. Start by declaring a lambda function using the func keyword, followed by the function parameters enclosed in parentheses. For example:

func(x int) int {
    return x * x
}

1. Specify the return type of the lambda function after the parameter list, separated by a space and a return type. For example, (x int) int indicates that the lambda function takes an integer parameter and returns an integer value.

2. Define the function body inside curly braces {}. This is where you write the logic of the lambda function. For example, the lambda function func(x int) int { return x * x } squares the input parameter x and returns the result.

3. Assign the lambda function to a variable if you want to use it later. For example:

square := func(x int) int {
    return x * x
}

1. Call the lambda function by using the variable name followed by parentheses and passing the required arguments. For example, square(5) will return 25.

Lambdas in Go are often used in higher-order functions, where functions can be passed as parameters or returned as results. They provide a concise way to define and use small, reusable pieces of code without the need for separate function declarations.

I hope this explanation helps you understand how to use lambdas in Go. Let me know if you have any further questions.
