The if statement is the fundamental control statement that allows JavaScript to make decisions and execute statements conditionally. SyntaxThe syntax for a basic if statement is as follows −if(expression){ Statement(s)to be executed if expression is true }Here a JavaScript expression is evaluated. If the resulting value is true, the given statement(s) are executed. If the expression is false, then no statement would be not executed. Most of the times, you will use comparison operators while making decisions.ExampleYou can try to run the following to learn how to work with if statement in JavaScript −Live Demo ... Read More

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

In this tutorial, we will learn about the multiplication operator (*) in JavaScript. The multiplication operator is a binary operator which requires at least two operands to operate on. The multiplication operator simply multiplies the left operand with the right operand, or you can say that it simply increases the value of the left operand with the same value till the value of the right operand becomes zero. The example below will explain you everything − 3 * 2 = 6 OR 3 + 3 = 6 5 * 3 = 15 OR 5 + 5 + 5 = 15 ... Read More

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
