Filter null from an array in JavaScript?
To filter null from an array and display only non-null values instead, use filter(). Following is the code −
Example
var
names=[null,"John",null,"David","","Mike",null,undefined,"Bob","Adam",null,null];
console.log("Before filter null=");
console.log(names);
var filterNull=[];
filterNullValues=names.filter(obj=>obj);
console.log("After filtering the null values=");
console.log(filterNullValues);To run the above program, you need to use the following command −
node fileName.js.
Output
Here, my file name is demo148.js. This will produce the following output −
PS C:\Users\Amit\JavaScript-code> node demo148.js Before filter null=[ null, 'John', null, 'David', '', 'Mike', null, undefined, 'Bob', 'Adam', null, null ] After filtering the null values= [ 'John', 'David', 'Mike', 'Bob', 'Adam' ]
