Julia is a promising new language that: Has native performance, close to or sometimes even exceeding C++ or Fortran; Solves the multiple language issue, one language for everything (including GPU); Is as easy to get into as Python or R; Is designed for parallel computing.Julia is a promising new language that: Has native performance, close to or sometimes even exceeding C++ or Fortran; Solves the multiple language issue, one language for everything (including GPU); Is as easy to get into as Python or R; Is designed for parallel computing.This lesson teaches how to do efficient computation with Julia.
