Expose class functions to a function created using a string in JavaScript?

I need to run bunch of scripts saved in text. I need to convert them to JavaScript during runtime and it may have some calls to some functions within that class to get some data, like shown below. Basically I need to expose functions of the class to those scripts being run in one of the function of the same class. It works fine as long as I do not make calls to randomNumbers() function and hard code some numbers. I'll appreciate any feedback on this. thank you,

   var config = {
    minX: 1,
    maxX: 10,
    get randomIntFromInterval() {
        return (() =>
            Math.floor(Math.random() * (this.maxX - this.minX + 1) + this.minX)).bind(
                config
            );
    },
};
        
        
        export const executeFns = () => {
            let edit = `
            let a = randomIntFromInterval();
            let b = randomIntFromInterval();
            if (a> b) {
            console.log('a is bigger than b')
            } else if (b>a) {
            console.log('b is bigger than a')
            }
            console.log('a',a );
            console.log('b',b )`;
        
            var f4 = NamedFunction('fancyname', [], edit, config);
            f4();
        };
        
            export function NamedFunction(name, args, body, scope, values) {
                if (typeof args == 'string') {
                    values = scope;
                    scope = body;
                    body = args;
                    args = [];
                }
            
                if (!Array.isArray(scope) || !Array.isArray(values)) {
                    if (typeof scope == 'object') {
                        var keys = Object.keys(scope);
                        values = keys.map(function (p) {
                            return scope[p];
                        });
                        scope = keys;
                    } else {
                        values = [];
                        scope = [];
                    }
                }
                return Function(
                    scope,
                    'function ' +
                        name +
                        '(' +
                        args.join(', ') +
                        ') {\n' +
                        body +
                        '\n}\nreturn ' +
                        name +
                        ';'
                ).apply(null, values);
            }

Prop `className` did not match in next js app

I have written a sample code ( Github Link here ). this is a simple next js app, but giving me error when I refresh the page. This seems to be the common problem and I tried the fix provided in the internet but does not seem to fix my issue. The error is Warning: Prop className did not match. Server: "MuiBox-root MuiBox-root-1" Client: "MuiBox-root MuiBox-root-2". Did changes for _document.js, modified _app.js as mentioned in official website and solutions in stackoverflow. but nothing seems to work. Could someone take a look and help me whats wrong with the code? Via Active questions tagged javascript - Stack Overflow https://ift.tt/2FdjaAW
