JavaScript - check if string is empty
0 points
In this article, we would like to show you how to check if string is empty in JavaScript.
Quick solution:
xxxxxxxxxx1
const myString = '';2
3
if (myString === '') {4
console.log('myString is empty');5
} else {6
console.log('myString is not empty');7
}
In this example, we create a custom function that checks if the string is empty.
xxxxxxxxxx1
const isEmpty = (string) => {2
return string ? false : true;3
};4
5
console.log( isEmpty('') ); // true6
console.log( isEmpty('sample text') ); // falseNote:
This solution can be used to check if the string is
nullorundefinedtoo.
