Hello Everyone , 

i am currently working as a Siebel Developer, and now I’m interested to learn Salesforce. I’m new to Salesforce so request for suggestions to go for which certification and from should I get the video tutorials. 

As I have one plus experience in Siebel development and I’m familiar with JavaScript, eScript, HTML, css, I decided to go for JavaScript Developer 1 and PD 1 certificate. 

Request to please advice which one should be better option for me?
