Logical Operator

if conditions are used to run any statement.

Statement does not run until unless condition get true.

Logical operators are used if we need to check more than 1 condition in any statement.

If (condition1 && condition2){
}

&& = If both condition are true then the statement will run
If any condition is false then code will not run

If (condition1 || condition2){
}

|| If any one condition is incorrect code statement will run.

<script>
var age="18";
if(age >=18 && age<= 18){
document.write("Yes you are eligible")
}
</script>

Following is another code example of Logical OR ||

<script>
var jan= 5000;
var feb = 9000;
var march = 6000;
if(jan >= 4000 && feb >= "5000" && march >="8000" ){
document.write("Yes you are eligible")
}
else{
window.alert("you are not eligible")
};
</script>
