COMPARISON OPERATORS :

OPERATOR	DESCRIPTION
(==) equal to	compares two values to see if are the same
(!=) not equal	compares two values to see if are not the same
(===) strict equal to	compares two values to check that both the data type and value the same
(!==) strict not equal to	compares two values to check that both the data type and value are not the same
(>) greater than	check if the number in the left is greater than the number on the right
(<) less than	check if the number in the left is less than the number on the right
(>=) greater than or equal	check if the number in the left is greater than or equal the number on the right
(<=) less than or equal	check if the number in the left is less than or equal the number on the right

(||) logical or	test at least one condition
(!) logical not	takes a single boolean value and inverts it

LOOPS

loops check a condition , if it returns true , a code block will run , and the condition will be checked again and if it still retuns true , it's repate until the condition returns false

1) For loop :

for(var i=0; i<10; i++) { document.write(i) }

for : keyword (var i=0; i<10; i++): condition (counter) {document.write(i)} : for bblock code

about condition (counter ) is contian :

1. initialization var i=0 ;
2. condition i<10;
3. update i++

start loop when i=0;

run the code and the i increment

if the condition still TRUE , repate the code

1) while loops :

var i = l ;
var msg = ' ' ;
II Set counter to 1
II Message
II Store 5 times tabl e in a variable
while (i < 10) {
msg += i + ' x 5 = ' + (i * 5) + '<br I>';
i++;
}
document .getEl ementByid( ' answer') . innerHTML = msg;

This loop will continue to run for as long as the condition in the parentheses is true. That condition is a counter indicating that, as long as the variable i remains less than 10, the statements in the subsequent code block should run.
