Usage

To use the String Calculator function, simply call it with a string representing the arithmetic expression you want to evaluate. For example:

const result = stringCalc("100-10/2x0+5");
console.log(result); // Output: 105

The function will parse the input string and calculate the result according to the standard rules of arithmetic.

• "100-10/2x0+5" => 105
• "10+20-5" => 25
• "50x2/5" => 20
• "100/2x3" => 150
• "100/(2x3)" => 20

Error Handling

The function does not currently handle invalid input strings or edge cases such as division by zero. Therefore, it's important to ensure that the input string follows the expected format and does not contain any errors.
