Looping Constructs
Looping is a core concept in programming. Mathematica provides powerful primitives for specifying and controlling looping, not only in traditional procedural programming, but also in other, more modern and streamlined programming paradigms.
Do evaluate an expression looping over a variable: Do[expr, {i, n}]
    
While evaluate an expression while a criterion is true: While[crit, expr]
For a "for loop": For[init, test, incr, body]
    
Table build up a table by looping over variables: Table[expr, {i, n}]
    
Nest  ▪ NestWhile  ▪ FixedPoint  ▪ Fold  ▪ ...
    
Scan  ▪ Map(/@ ▪ MapIndexed  ▪ ReplaceRepeated(//. ▪ ...
    
Loop Termination
Throw exit any loop, going to the nearest enclosing Catch
Break  ▪ Continue  ▪ Return  ▪ Interrupt  ▪ Abort
