What are the differences between blocks, procs, and lambdas in Ruby?

Can you explain the differences between blocks, procs, and lambdas in Ruby?

Sure! In Ruby, blocks are chunks of code that can be passed to methods, while procs and lambdas are objects that encapsulate blocks.

What are the key differences in how they handle arguments?

Blocks can take a variable number of arguments, while procs and lambdas have stricter argument handling. Lambdas check the number of arguments, while procs do not.

How do they differ in terms of return behavior?

A return statement in a lambda will exit the lambda itself, while a return in a proc will exit the enclosing method.

Can you give me an example of when to use each?

Use blocks for simple callbacks, procs for reusable code snippets, and lambdas when you need strict argument checking.
