Key Points to learn SFDC

I’m working as a Salesforce Developer on force.com platform and Independently perform development, testing, implementation, documentation, deployment and updating applications related to Salesforce.

I am a Salesforce Certified developer having 2.5 years of experience on Force.com plateform. I have worked on almost every aspect of Force.com plateform like Apex classes, VF pages, Apex Trigger, Data-loader, Batch-Classes,SOQL, SOSL,Email services,Work Flow rules,Approval process,Email Template, Rest APi, etc. I’ve experience to integrate Salesforce platform with various third party like Google Drive, Box.com, Drop-Box,,Facebook, Heroku etc using Salesforce Rest APi. I’ve created some application using Salesforce.com,Javascript,Jquery,CSS,Bootstrap

Salesforce Trailhead is a very good resource to learn salesforce:https://developer.salesforce.com/trailhead .

Salesforce has launched its own interactive learning tool i.e. Trailhead which will be good place to start learning and it is absolutely free as of now. It has three different levels modules beginner,Intermediate and advanced.

Here’s what I recommend:

1. Learn the non-code side of Salesforce first. You absolutely cannot be a good Apex programmer unless you know core Salesforce extremely well.
2. If you are know about Java programming then it will be much easier for you to learn Salesforce coding side,Otherwise Start learning Java Basics. There are a ton of great books on Java. The good news is there is 95% overlap between the two languages.My favorite book was Head First Java.
3. Next work through the Visualforce Developers Guide — every developer creating Visualforce pages.you’ll be amazed at how much you can achieve without Apex controller or a single SOQL query.
4. You need to start with Force.com Fundamentalhttps://developer.salesforce.com/page/Force_Platform_Fundamentals Once you’re ready to learn Apex, start off with a simple Hello World trigger. Then move on to SOQL. Then, combine SOQL and Apex. From there, you want to learn about Governor Limits, batch Apex, Visualforce, etc.

You must unit test to deploy out of a development sandbox to a production server, too. And you must have decent test coverage.At least 75%.

Yes, programming is limited.There is a 100+ page document that explains this. SFDC calls these governor limits. You must abide by them or your code will crash.

n my initial career,I have spent most of my time in salesforce documentation because documentation is awesome.It gives us deep detail about every module of salesforce.

Salesforce was the first organization to provided the SaaS (Software as a Service) but in more advanced way.
Working as a Developer on Salesforce platform will give you more chances on Development side as there are multiple projects which are still being enhanced or organization want to build their project on the same.

report from Gartner — indicated that Salesforce is the most popular solution by a substantial margin, and new announcements from the developer suggest the cloud-based CRM will continue to dominate the market.
Its going to be absolutely brilliant. You can be proud of it, keep updating yourself with salesforce. Sharpen your skills more and more to grow more.

Apart from the as a personal experience, you might wanna spend some time on these channels to learn & ask question and answers regarding salesforce:

1. Developer Boards which includes Salesforce @ Stackexchange and Force.com Developer Boards.
2. Admin Boards which includes Success Community.
3. Social Forums like LinkedIn, Facebook, Twitter.

I love Salesforce. The beauty of Salesforce lies in its user community. There is a lot of help out there by developers,admins and through MVP’s.It’s salesforce own developer community.
