check if a column exists in a SQL Server table

Delay before recursive function call

Anderson

I'm trying to set a delay before every recursive function call. Currently, it's returning undefined. The problem might be the scope of the recursive call (inside settimeout and then). I tried it like this:

        function delay(ms) {
            return new Promise(resolve => {
                setTimeout(resolve, ms)
            });
        } 

        const checkIfListElementIsRendered = (className) => {
            delay(10).then(function (res) {
                if (document.getElementsByClassName(className)[0]) {
                    return true;
                }
                return checkIfListElementIsRendered(className);
            })
        }

And this:

        const checkIfListElementIsRendered = (className) => {
            if (document.getElementsByClassName(className)[0]) {
                return true;
            }
            
            setTimeout(() => {
                return checkIfListElementIsRendered(className);
            }, 10);   
        }

Any help is appreciated!
