JavaScript/ Typescript object null check?
For null check, you can use ! condition.
Example
Following is the code −
var value=null; if(!value) { console.log("This is null."); } else { console.log("This is not null."); }
To run the above program, you need to use the following command −
node fileName.js.
Here, my file name is demo305.js.
Output
This will produce the following output −
PS C:\Users\Amit\javascript-code> node demo305.js This is null.
