Assignments generally make it possible for a variable to carry different values at various instances during its existence-span and scope. On the other hand, some languages (primarily strictly functional) usually do not enable that sort of "harmful" reassignment, as it might suggest modifications of non-area condition. The purpose is always to enforce referential transparency, i.e. capabilities that don't count on the condition of some variable(s), but generate precisely the same success to get a provided set of parametric inputs at any position in time.
