Advice on where/how to learn MQL4 ?

Hello everyone
I want to ask if there is any course or a guide for MQL4 programming for a beginner. I searched on google I haven't found any, though I see many MQL4 developer but wonder from where did they learned all language skills.
I know Java, C#, C, SQl, and HTML/CSS/Javascript if it comes to basic programming other than that I am not really into IT much as I had been just focusing on trading only.
I am ready to put my time to learn the language but I just don't find any book or guide or anything that is not too much basic, for example I do know what are data types, functions, variables, looping, classes, sub-looping etc but I do not find anything above it.
Any help is appreciated.

Focus on MQL5 instead. MQL4 sooner or later disappear.

Also, Jim Dandy has an online course you can take which allows you to ask questions if you run into problems or need a concept or idea clarified.

Hope this helps.
