Question

Section 3: Create a Calculator For this problem, please create a "calculator" function that takes two integers and an operator and does the math operation corresponding to the numbers and the operator. For instance, calculate(5,"+", 6) should return 11. Please support the following operators: +- X/^(addition, subtraction, multiplication, division, exponentiation) 1 2 3 function calculate (numi, operator, num2) { // Do the calculation } RUN CODE Parameters Expected Result Actual Result 1,"+", 4 1,"x", 0 20,"7", 5 3,"", 3

Answer 1

CODE:

function calculate(number1,operator,number2){
if (!number1 || !number2){
return "Invalid number"
}
if (!['*','-','/','+','^'].includes(operator)){
return "Invalid operator"
}
switch(operator){
case "+":
return number1 + number2;
case "/":
return number1 / number2;
case "*":
return number1 * number2;
case "-":
return number1 - number2;
case "^":
return number1 ** number2;
}
}

To call the function:

calculate(1,"+",4)

calculate(7,"-",2)

calculate(5,"*",1)

calculate(20,"+",5)

calculate(3,"+",3)

Output:

> calculate(1,"+",4) < 5 calculate(7,"-",2) < 5 calculate(5,"*",1) <-5 calculate(3,"A", 3) <- 27

Please give thumbsup...
