Topic Name : Hidden Use of eval

[divyanshu-rawat]

setTimeout and setInterval can also take a string as their first parameter.

function foo() {
    // will get called
}

function bar() {
    function foo() {
        // never gets called
    }
    setTimeout('foo()', 1000);
}
bar();

In node v7.3.0
Here setTimeout('foo()', 1000); will throw TypeError: "callback" argument must be a function
