This project helped me learn how to use event listeners and learn how to implement the shunting-yard algorithm (infix to postfix) to preprocess user-inputed expressions to be computer readable.\n\n# Future improvements\n- Add event listeners to keyboard keys to make it easier for clients to input expressions\n- Make implicit multiplication and division with parenthesis\n- Add other operations (log, sin, cos, tan, ..., etc)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fallenjue%2Finfix-to-postfix-calculator","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fallenjue%2Finfix-to-postfix-calculator","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fallenjue%2Finfix-to-postfix-calculator/lists"}
