Julia global Keyword | Creating a global variable in Julia
Keywords in Julia are reserved words whose value is pre-defined to the compiler and can not be changed by the user. These words have a specific meaning and perform their specific operation on execution.
'global' keyword in Julia is used to access a variable that is defined in the global scope. It makes the variable where it is used as its current scope and refers to the global variable of that name.
var1 = value1 loop condition statement global var1 = value2 statement end
With the use of global variable, the value of variable x can be accessed from anywhere in the code.
