I have an object of functions id, names and parameters.
I want to call the object with an id, that will execute the corresponding function by its string name and passes the associated array parameters.
var funcList = {
"0abc1": {
fn: "myFunc1",
args: ["red", "green"]
},
"1def2": {
fn: "myFunc2",
args: ["blue"]
}
};
const func = funcList["0abc1"];
const funcName = func.fn;
const funcParams = func.args;
window[funcName](funcParams.toString());
When the function has one parameter it works. But doesen’t work with multiple parameters.
Is there a better way to implemented it or correct it ?

If the function has multiple arguments then you can use Spread syntax to pass the array entities to the function individually, instead of as a single string:
var funcList = {
"0abc1": {
fn: "myFunc1",
args: ["red", "green"]
}
}
const func = funcList["0abc1"];
const funcName = func.fn;
const funcParams = func.args;
window[funcName](...funcParams);
function myFunc1(color1, color2) {
console.log(color1);
console.log(color2);
}
