points
In this article, we would like to show you how to check if string is empty in JavaScript.
Quick solution:
// ONLINE-RUNNER:browser;
const myString = '';
if (myString === '') {
console.log('myString is empty');
} else {
console.log('myString is not empty');
}
Practical examples
In this example, we create a custom function that checks if the string is empty.
// ONLINE-RUNNER:browser;
const isEmpty = (string) => {
return string ? false : true;
};
console.log( isEmpty('') ); // true
console.log( isEmpty('sample text') ); // false
Note:
This solution can be used to check if the string is
nullorundefinedtoo.
