const splitString = (text, delimiter) => {
    const index = text.indexOf(delimiter);
    if (index === -1) {
        return [text];
    }
    return [
        text.substring(0, index),
        text.substring(index + 1)
    ];
};


// Usage example:

const text = 'a,b,c';
const parts = splitString(text, ',');

console.log(parts);  // ['a', 'b,c']
