var weekdays = ["Mon", "Tue", "Wed", "Thur", "Fri"]; for(var x=0; x < weekdays.length; x++){   document.write(day+"|"); } //Output is "Mon|Tue|Wed|Thur|Fri|"

The best method to iterate through JavaScript arrays is to use a for(init; condition; adjustment){LOOP_BLOCK} loop. The for() loop allows you to initialize a variable and then iterate through until a condition is met. To loop through the array, initialize an index and then stop the loop when the index is equal to the length of the array.
