To do the project, we will be using an inbuilt function ‘eval’ that takes a set of characters or equations as an argument and returns the final output of that equation.
Objectives:
The objectives for creating a calculator using JavaScript are as follows:
To understand the basic concepts of JavaScript, including variables, functions, and event handling.
To learn how to create an interactive user interface using HTML and CSS.
To use JavaScript to perform mathematical operations and display results on the screen.
To handle user input and perform operations in response to button clicks.
To apply error handling techniques to prevent unexpected behavior.
To build a functioning calculator from scratch and extract data from buttons pressed by the user and then calculate the result and display it on the screen.
Requirements:
A text editor to write and edit HTML, CSS, and JavaScript code.
A web browser to test and run the calculator.
Basic knowledge of HTML and CSS.
A basic understanding of JavaScript concepts such as variables, functions, and event handling.
Familiarity with arithmetic operations such as addition, subtraction, multiplication, and division.
A basic understanding of error-handling techniques in JavaScript.
The three main languages we use to build this JavaScript calculator are HTML, CSS, and JavaScript. JavaScript is the programming language to apply the logic. We have used HTML to structure the site and CSS to design and layout of our webpage.
