This exercise asks you to replicate the functionality of the popular image_tag method provided by the Ruby on Rails framework.
Build a program that replicates the functionality of the
image_tagmethod provided by the Ruby on Rails framework.
The method should be able to dynamically generate an HTML image tag. Specifically it needs to be able to take in any number of arguments and integrate the arguments and their values as elements contained in the generated image tag.
@image_path = "https://devcamp.com/some_pic.jpg" image_tag(@image_path)) # "<img src='https://devcamp.com/some_pic.jpg'>" image_tag(@image_path, width: 42)) # "<img src='https://devcamp.com/some_pic.jpg' width='42'>" image_tag(@image_path, alt: "My Image") # "<img src='https://devcamp.com/some_pic.jpg' width='42' alt='My Image'>"
