Utilizing Typescript for extracting coordinates from regular expressions

I'm currently working with Typescript and I've been exploring the idea of using regular expressions for a certain task.

The input data is in the form of a string:

"(0,1)(1,2)(3,1)"

There are several validations that need to be performed on this data:

Every value should be a numeric digit.
Each number must not exceed a certain variable value x set at runtime.
If all validations pass, I would like to extract the matches into an array while removing the parentheses around them.

Do you think this can be achieved using regular expressions?

Having a JavaScript question, you can make use of regular expressions and additional logic to achieve the desired solution:

const validateCoordinates = (inputString: string, maxValue: number) => {
    const match = inputString.match(/\((\d+),(\d+)\)\((\d+),(\d+)\)\((\d+),(\d+)\)/);
    if (match) {
        const results = match.slice(1, 7);
        const pass = results.every(item => Number(item) < maxValue);
        if (pass) {
            return results.map(n => Number(n));
        }
    }

    return false;
};

validateCoordinates('(1,1)(1,2)(3,1)', 3); // false 
validateCoordinates('(1,1)(1,2)(3,1)', 5); // [ 1, 1, 1, 2, 3, 1 ]
validateCoordinates('(1,1)(1,2)(3,1s)', 5); // false
