If I use some packages like Gadfly, each run can take up to 1 minute or even longer.It is kinda frustrating to wait to see how my new written function works. You can the language. compilers) that has long existed in programming: . Without going into a long discussion, Julia solves a trade-off (partially thanks to the recent developments in just-in-time compilers) that has long existed in programming: fast coding vs. fast execution.

However, none of this stuff really matters on a It was also designed to utilize the strongest aspect of other programming languages such as speed and openness The language is mainly used for data processing and scientific computing. acquainted with the basic features of the language. You can also use the Revise.jl package for a finer control over what Julia keeps in memory during a work session. You can also choose, at least to start with, not to install Julia at all, and try JuliaBox, a free online IJulia notebook server that you access from your browser, instead. exercise in suffering. Note: in recent versions of Julia, there is a --compile=min option Note status Retrieves a list with name and versions of locally installed packages, update Updates your local index of packages and all your local packages to the latest version, add myPkg Automatically downloads and installs a package, rm myPkg Removes a package and all its dependent packages that has been installed automatically only for it, add pkgName#masterCheckouts the master branch of a package (and free pkgName returns to the released version), add pkgName#branchNameCheckout a specific branch, add [email protected]:userName/pkgName.jl.git Checkout a non registered pkg.
