if you need to do so, you can manually add custom functions and save them to the database. Next time, you need to get all the functions and execute them in turn to get the results. Doesn"t it become a string when it is saved in the database? how to execute these strings in turn to get the results of the custom function
new Function(/*your code string*/);
//or
eval(/*your code string*/)add some examples
//
const codeString = `function abc(){
console.log("hello world")
}`;
//1
const myABC = new Function(`return ${codeString}`)();
myAbC();//hello world
//2
eval(`var myABC2 = ${codeString}`);
myABC2();//hello worldthe above is the implementation of your requirements.
