Lambda

TODO

• Lambda on ApplicationRecord models

Basic lambda creation and calling example:

[31] pry(main)> print_lambda = lambda { puts "hello world" }

=> #<Proc:0x00007f9d96908ab8@(pry):39 (lambda)>

[32] pry(main)> print_lambda.call

hello world

Creating lambda with ->

[33] pry(main)> print_lambda = -> { puts "hello world" }

=> #<Proc:0x00007f9d969dfce8@(pry):41 (lambda)>

[34] pry(main)> print_lambda.call

hello world

Lambda with parameters

temp_lambda = lambda { |first_param, second_param| puts "#{first_param} - #{second_param}" }

temp_lambda.call(1, 2)

# Output:

$ruby main.rb

1 - 2
