MDN Control Flow

Control flow is the way the computer executes commands; statetments in a script

conditionals and loops are the frequent commands given to a computer

conditional structure is a if…else command; like when a user forgets to fill something in

if (field==empty) { promptUser(); } else { submitForm(); }

scripts can be set up for when an event is occured, a command

order of execution matters

most basic statement

{ statement_1; statement_2; ⋮ statement_n; }

block statemenst used with (if, for, while)

while (x < 10) { x++; }

true, false statement is a boolean

if (condition_1) { statement_1; } else if (condition_2) { statement_2; } else if (condition_n) { statement_n; } else { statement_last; }

don’t do x=y for if..else statements if (x = y) { /* statements here */ }
