Is the value an object or an array but not null?

Deep check if an identifier is defined and not null

A micro-package to check if a value is not null. With proper TS typing!

Check if something exists (e.g. not null || undefined)

Basically, SQL COALESCE in JavaScript; return the first value that is not null.

Return the first argument that is `!= null`

Determine if a variable is set and is not NULL

**`exists`** returns `true` if its argument is not `null` or `undefined`.

Checks whether an object is not null or a function or a brisky-base object

Simple set of functions to check variables. Includes check of undefined / defined / defined and not null / defined and not empty / is number / is function is object

ensures all required parameters are not null, or throws a useful error like 'phone is required'

``` CREATE TABLE IF NOT EXISTS `txt` ( `id` bigint(20) unsigned NOT NULL AUTO_INCREMENT, `hash` binary(32) NOT NULL, `val` longtext DEFAULT NULL, PRIMARY KEY (`id`) /*T![clustered_index] CLUSTERED */, UNIQUE KEY `hash` (`hash`) ); ```

criterion allows you to work with (build, combine, reuse, ...) SQL-where-conditions ('x = 5 AND y IS NOT NULL'...) as data (goodbye string-concatenation) and compile them to SQL: it has a succinct mongodb-like query-language, a simple and elegant function

create table object_class ( id int(10) unsigned not null auto_increment, create_time datetime not null default current_timestamp, name varchar(255) default null, scope varchar(100) default null, code varchar(100) not null, primary key(id) ) en

Vue 3 type guard checking if ref value is not null/undefined

A lightweight utility to check if an object is not empty, not null, or not undefined.

TypeScript predicates and type guards for nullish values, booleans, non-empty values, and renderable React nodes

Like which(1) unix command. Find the first instance of an executable in the PATH.

A utility to test if a 'value' has a type of 'Object' and is not null

A one-liner to check if a property is set (not null, undefined or empty string).
