Var newParagraph1 = document.createElement('p') //creates a new paragraph element NewParagraph.appendChild(newText) //created text is appended to the paragraph element createdĭ(newParagraph) // created paragraph and text along with output is appended to the document body Var newText = document.createTextNode('The number is between 5 and 10') //creates text along with ouput to be displayed

Var newParagraph = document.createElement('p') //creates a new paragraph element Var no = document.getElementById('no').value The following web document demonstrates the use of AND operator (&). So we can conclude that if and only if, both of the conditions are TRUE or 1, LOGICAL AND operations returns TRUE or 1. Which explains that if both of conditions are TRUE or 1, the return is TRUE or 1. In fig.-4 of the picture, both of the taps are open, so the water is flowing down. Which explains that even if any of conditions are FALSE or 0, the return is FALSE or 0. In fig.-2 of the picture, one of the taps are closed, even then, the water is not flowing down. Which explains that if both of conditions are FALSE or 0, the return is FALSE or 0. In fig.-1 of the picture, both of the taps are closed, so the water is not flowing down. Then, the switch statement executes cases based on the user input.This above pictorial helps you to understand the concept of LOGICAL AND operation with an analogy of taps and water.

In above program, the user is asked to enter either +, -, * or /, and two numbers. The if.else if.if statement is used to check the condition that the user has entered for the operator. The corresponding operation is performed and the output is displayed.Įxample 2: Simple Calculator with switch // program for a simple calculatorĬonst operator = prompt('Enter operator ( either +, -, * or / ): ') Ĭonst number1 = parseFloat(prompt('Enter first number: ')) Ĭonst number2 = parseFloat(prompt('Enter second number: ')) Ĭonsole.log(`$`)
