Detailed explanation-1: -JavaScript has an even more succinct syntax to increment a number by 1. The increment operator ( ++ ) increments its operand by 1; that is, it adds 1 to the existing value. There’s a corresponding decrement operator (–) that decrements a variable’s value by 1 . That is, it subtracts 1 from the value.
Detailed explanation-2: -JavaScript can “display” data in different ways: Writing into an HTML element, using innerHTML . Writing into the HTML output using document.write() . Writing into an alert box, using window.alert() .
Detailed explanation-3: -The while loop starts by evaluating condition . If condition evaluates to true, the code in the code block gets executed. If condition evaluates to false, the code in the code block is not executed and the loop ends.
Detailed explanation-4: -The “for” loop Executes once upon entering the loop. Checked before every loop iteration. If false, the loop stops. Runs again and again while the condition is truthy.
