- Using the typeof Operator and length Property:
- Check if the variable is a string and its length is 0
let str = "";
if (typeof str === "string" && str.length === 0) {
console.log("The string is empty");
}
- Using the length Property Directly:
let str = "";
if (typeof str === "string" && str.length === 0) {
console.log("The string is empty");
}
If you accidentally push a .env
file to a remote repository, you should immediately take steps to remove it and add it to .gitignore
to prevent it from being tracked in the future. Here are the detailed steps:
Use the git filter-branch
command to rewrite the history of your repository and remove the file. Replace PATH-TO-YOUR-FILE
with the actual path to the .env
file in your repository.
git filter-branch --force --index-filter\
"git rm --cached --ignore-unmatch PATH-TO-YOUR-FILE"\
To implement pagination for an HTML table in a Next.js project with Tailwind CSS, you can follow these steps:
useState
hook from React to create these states. The initial value for the current page can be 1, and the initial value for the number of rows per page can be 10.const [currentPage, setCurrentPage] = useState(1);
const [rowsPerPage, setRowsPerPage] = useState(10);
