Building an MVP is a crucial step for getting your SaaS product off the ground. While most teams who don’t understand the inner workings of building a product might think that getting your foot off the ground will take a large amount of cash, that doesn’t have to be the case.

There is a great amount of enthusiasm when you start your own business. It is truly amazing to see what started as just an idea become a real thing. However, motivation is not a guarantee of success. Unfortunately, less than 50% of businesses make it to their 5th year, and only 33% make it to 10 years. A massive 82% of businesses fail because of cash flow problems. For this reason, your burn rate is an essential figure that you have to be aware of.

With dynamic nested forms, you can create forms that automatically calculate fields based on the information that has been entered into previous fields. If you’re building a form for your online store, for example, you might want to create a product listing form with several different fields: name, category and price. If the user selects “blue jeans” as their category and then enters $50 as their price, then the form will automatically calculate all of the necessary information—including tax—and display it in an easy-to-read format.

Before Rails 5, all constants were loaded via ‘autoloading’ when the application booted up. Rails 5 replaced this with ‘eager loading,’ i.e loading all the constants even before they are actually needed. With ‘autoloading,’ the application does not load the constant until it is needed. Once a class is needed, if it is missing then the application starts looking in ‘autoload paths’ to load it. Eager_load_paths contains a list of directories. When the application boots then it loads all constants found in all directories listed in eager_load_paths.

There are many use cases that require an href link to be applied to an entire div. One such situation required an href to be applied to this entire icon in order to make it clickable:
