It performs XOR operation on the right operand with the left operand and assigns the result to the left operand.ExampleYou can try to run the following code to learn how to work with Bitwise XOR Assignment OperatorLive Demo                    var a = 2;   // Bit presentation 10          var b = 3;   // Bit presentation 11          document.write("(a ^= b) => ");          document.write(a ^= b);          

The “double tilde” (~~) operator is a double NOT Bitwise operator. Use it as a substitute for Math.floor(), since it’s faster.ExampleYou can try to run the following code to learn about double tilde operator −                    var a = 2;          var b,c, d;          b = ~~a;          c = Math.floor(a);          d = ~~b=== c;          document.write(b);          document.write(""+c);          document.write(""+d); // They are equal          

The addition operator is used to add two operands.ExampleYou can try to run the following code to work with Addition Operator −                    var a = 33;          var b = 10;          document.write("a + b = ");          result =a + b;          document.write(result);          

It adds the right operand to the left operand and assigns the result to the left operand.ExampleYou can try to run the following code to learn how to work with Addition Assignment Operator −                    var a = 33;          var b = 10;          document.write("Value of a => (a += b) => ");          result = (a += b);          document.write(result);          document.write(linebreak);          

In this tutorial, we will learn about the modulus operator in JavaScript. In some languages, the modulus operator is also known as the remainder operator. The remainder operator and the modulus operator both are used to get the remainder of an integer when it is divided by some other integer, but they are different from each other in case of signs of the remainder whether it has to be positive or negative that is returned after the division. In the expression a % b, a is called dividend, while b is known as divisor. In case of the modulo, the ... Read More

To redirect from an HTML page, use the META Tag. With this, use the http-equiv attribute to provide an HTTP header for the value of the content attribute. The value of the content is the number of seconds; you want the page to redirect after.Through this, you can automatically redirect your visitors to a new homepage. Set the content attribute to 0, if you want it to load immediately.ExampleThe following is an example of redirecting current page to another page after 2 seconds.Live Demo           Redirection                     This page will redirect in 2 seconds.    

In this tutorial, we learn to use JavaScript to redirect a webpage after 5 seconds. To redirect a webpage after 5 seconds, use the setInterval() method to set the time interval. Add the webpage in window.location.href object. As we know, whenever we need to call a function or some block of code after a specific delay of time we use the setTimeout() and the setInterval() methods of JavaScript. Lts look at the use of these methods to redirect a web page by 5 seconds. To redirect a page we will use the document.location.href or window.location.href object of JavaScript as shown ...

This operator is just like the >>operator, except that the bits shifted in on the left are always zero i.e. xeroes are filled in from the left.ExampleYou can try to run the following code to learn how to work with unsigned right shift operator −                    var a =-14;          var b =2; // Shift right two bits          document.write("(a >>> b) => ");          result =(a >>> b);          document.write(result);          

Double equals (==) is abstract equality comparison operator, which transforms the operands to the same type before making the comparison. For example,4    ==  4        // true '4'  ==  4        //true 4    == '4'       // true 0    == false     // trueTriple equals (===) are strict equality comparison operator, which returns false for different types and different content.For example,4 === 4  // true 4 === '4' // false var v1 = {'value':'key'}; var v2 = {'value': 'key'}; v1 === v2 //false

In this tutorial, we learn to use JavaScript to load a webpage after 5 seconds. We use the setTimeout() function in JavaScript to load a webpage after some interval. This function waits for some seconds and then loads the web page. We could also apply the setInterval() method to perform our task. Generally, a web page loads immediately if the network connection to which user connected is very strong, and if the network connection is very poor, then it will take some time to load. But did you know that, we can stop the web page loading for some time ... Read More
