I'm new to Javascript. I want to make this block run after the if statement is finished (asynchronous). The reason I want that is that I want to make some changes to update them if it falls into the if statement

let params = {
            TableName: "storepedia-test",
            Item: updatedItem
        };
    
        docClient.put(params, function (err, data) {
            if (err) {
                console.log(err);
            } else {
                res.redirect('/devices');
            }
        });

Here is my whole code

const { id } = req.params;
const file = req.file;
let updatedItem = { ...req.body};
updatedItem.id = id;
    if (file !== undefined){
        const deleteParams = {
            Key: updatedItem.image,
            Bucket: bucketName
        }
        s3.deleteObject(deleteParams, async (err, data) => {
            if (err) {
                console.log(err)
            } else {
                const result = await uploadFile(file);
                console.log('result', result);
                await unlinkFile(file.path);
                updatedItem.image = result.Key;
                let params = {
                    TableName: "storepedia-test",
                    Item: updatedItem
                };
            
                docClient.put(params, function (err, data) {
                    if (err) {
                        console.log(err);
                    } else {
                        res.redirect('/devices');
                    }
                });
            }
        })     
    } 

        let params = {
            TableName: "storepedia-test",
            Item: updatedItem
        };
    
        docClient.put(params, function (err, data) {
            if (err) {
                console.log(err);
            } else {
                res.redirect('/devices');
            }
        });
