Then, the switch statement executes cases based on the user input. To understand this example, you should have the knowledge of the following JavaScript programming topics: JavaScript if. In this example, you will learn to write a program to make a simple calculator in JavaScript. Now we perform some operation in the JavaScript program, as shown below. JavaScript Program to Make a Simple Calculator. In above program, the user is asked to enter either +, -, * or /, and two numbers. In this Calculator, we can perform basic operations like addition, multiplication, subtraction, and division. First, the structure of the calculator will be created (using HTML), then we will style it (using CSS) and finally, we will create the logic of the calculator (using JavaScript). 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(`$`) JavaScript (script.js) - To create logic of the calculator We will start building our calculator step by step.
