The for loop repeatedly executes a block of statements until a particular condition is true.
Syntax:
for(initialization; condition; statement){
//Block of statements
}
Where:
initialization statement: is used to initialize the loop variable.
boolean expression: is used for condition check whether returns true or false.
statement: is used for either increment or decrement of the loop variable.
JavaScript for loop example:
<html>
<head>
<script>
for (num=1; num<=10; num++) {
document.write(num + "<br/>")
}
</script>
</head>
<body>
</body>
</html>
