+Race Condition
+  Interleave: If I have 2 task and Order of execution between concurrent tasks
+  is not known, it's not determined, meaning it's not deterministic
+  It means these tasks can be interleaved in different ways.
+  Interleave is happening at the machine code level rather than the source code
+
+  Race condition is a problem where the outcome of the program depends on the interleaving
+  And Interleaving is non-deterministic.
+  It's determined by the operating system and the Go-runtime.
+  So, the interleaving can change every time you run it.
