 Learn from examples, not from language reference manual 
 
Get source code for examples that compile and execute.
1. You must be able to output at least an integer, a string,
   and a floating point number, initially just one method,
   there may be many methods, that comes later.

2. You need to know the commands to compile and execute the
   source code on your computer and operating system.
   At a minimum on, Windows, Linux, MacOSX.

3. You must be able to declare variables and list and arrays
   and matrix of various types.

4. You need to be able to have loops, iteration statements

5. You need  if then else  conditional statements

6. You need to be able to create functions, procedures,
   subroutines.

7. You need to be able to read and write files in various formats.

8. You need to be able to use a number of files combined to
   build a program. This may include packages, libraries,
   operating system commands, header files, etc.

9. If you or possibly others may use your code:
   Quickly translate working source code to 2 other languages.
   Then test source code on 3 operating systems Windows, Linux, MacOSX

Some languages have extra samples, such as math library

Then, sum language summaries

2018 most popular programming languages

programming language dates available

some history, dates, of programming languages

dates of hundreds of programming labguages

haskell and lisp are functional programming languages
R is best for statistics
matlab and mathematica are best for many math problems
fortran is still used and is the math libraries for matlab and python numpy
julia is one of the newest languages, still changing like many languages
swift is prefered for MacOSX and works on linux
Fortran, matlab, R and julia start subscripts at 1, not zero like most

  My programming experience recorded as counting files and lines of code
