What is the Alternatives to eval in JavaScript? how to convert code using a eval() to using Function()?

Question

I am getting a security error for the eval(). an error looks likes below.

Uncaught EvalError: Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of script in the following Content Security Policy directive: "script-src 'self' 'sha256-P/4RbWZ5tavHlZH3S2JukJ4toJ9iLwFkiBGYsngpgqo=' 'sha256-i4JIH9RhDp81FOGH3ZwoQRt2R4uvOYyeOmkCZoX6HeY=' 'sha256-3VlFnxIhSKloUaebh7I+Yjnu9vwMuwGEuqykqBQQLNw=' 'sha256-GHjvsztQyqr0koa6RWaeYUhRgrR/WcXa+NGlCwEpcLY=' 'sha256-3W2JH/z3DpHtF9okrA6TIFaJ6wFrL4gfTXfK5fjo1V0=' ssl.google-analytics.com

Below is my JS code.

eval(function (p, a, c, k, e, r) {
    e = function (c) {
        return (c < a ? '' : e(parseInt(c / a))) + ((c = c % a) > 35 ? String.fromCharCode(c + 29) : c.toString(36))
    };
    if (!''.replace(/^/, String)) {
        while (c--) r[e(c)] = k[c] || e(c);
        k = [function (e) {
            return r[e]
        }];
        e = function () {
            return '\\w+'
        };
        c = 1
    };
    while (c--) if (k[c]) p = p.replace(new RegExp('\\b' + e(c) + '\\b', 'g'), k[c]);
    return p

I am not much familiar with JS and CSP errors. can anyone help me with how to change this eval function?

Any help would be appreciated! Thanks :)
