Is there any syntax that does something similar to MATLAB's "clear" i.e. if I have a global variable "a". How do I get rid of it? How do I do the analog of
clear a

To clear all global variables, use clear global or clearvars –global . To clear a particular class, use clear myClass . To clear a particular function or script, use clear functionName . To clear all MEX functions, use clear mex .
Ctrl+J, Ctrl+C will clear the Console but not the Workspace: the variables and functions created are not cleared. You can clear the Workspace from the Console by pressing Ctrl+D to end Julia and Enter to start it again.
When you declare a variable as const , you are just telling something about how that name shall be used. So, it doesn't matter what content you assign to var2 the first time. If you don't declare it as const , there is nothing stopping you from assigning it a different value – maybe of a different type – later on.
let statements create a new hard scope block (see above) and introduce new variable bindings each time they run. Whereas assignments might reassign a new value to an existing value location, let always creates a new location.

Retrieved from the docs:
Julia does not have an analog of MATLAB’s clear function; once a name is defined in a Julia session (technically, in module Main), it is always present.
If memory usage is your concern, you can always replace objects with ones that consume less memory. For example, if A is a gigabyte-sized array that you no longer need, you can free the memory with A = 0. The memory will be released the next time the garbage collector runs; you can force this to happen with gc().
