js not equal to null
if (variable !== null) {
//code
}
//Or, if you're expecting null as a string ('null'):
if (variable != null) {
//code
}
//!== means not equal to, just like !=, but !== checks that the datatype is the same, whereas != doesn't.
//Example: (null !== "null") = true (null != "null") = falsejavascript check if not null
//Even if the value is 0, this will execute.
if (myVar !== null) {...}
//If you don't want it to execute when it's 0, then set it as
if (myVar) {...}
//This will return false if var value is 0.Copyright © 2021 Codeinu
