How do I filter out null values

I have a bunch of dates I need to convert to strings and put into an object.
sometimes however my date field is empty and it comes up as null

As far as I understand checking if something is truthy I can just check it with if(value) and it only runs if value is truthy - not null, undefined…

However even despite el.getCellValue(wipDate) comes up as null, my code still runs the blog inside the if statement.

Does anyone know what I’m doing wrong?

    let month = '';
    let year = null;
    let dateObj = {'year':year, 'month':months[month]};
        
    console.log(el.getCellValue(wipDate))   

    if(el.getCellValue(wipDate)){
        //console.log('inside')
        month = months[new Date(el.getCellValue(wipDate)).getMonth()]
        year = new Date(el.getCellValue(wipDate)).getFullYear()
    }

Hi Kim,

Hmm… I’m not able to reproduce what you’re describing, using this simple script:

let table = base.getTable('Table 1')
let query = await table.selectRecordsAsync();
let records = query.records;

for(let rec of records) {
    let date = rec.getCellValue('Date');
    output.inspect(date);
    if(date) {
        console.log('here');
    }
}

Here’s my table set up, and the results of my script:

We don’t have your full script so it’s hard to say exactly what might be going on, but hopefully that snippet I used might help identify any issues! If you’re able to share your entire script, showing how and where el is being set, that will also help.

Thank you @Erin_OHern
I have since reworked my script so I don’t have it any longer myself either.
I was just pretty sure it did not work - however it is definately possible I’ve starred myself blind on it and there was something leading up to it not working as anticipated.

I am having this issue with my script. It is iterating through a column that has linked record data in it (An Object) which is a person’s name.

The column name it is iterating through is ‘Primary Introducer (from Investor)’

Although not every cell in the column has an object in it. Some are empty. When that is the case I get an error.

Error Being:
TypeError: Cannot read properties of null (reading ‘0’)
at main on line 45

Any help would be appreciated

Script:

let lookupTable = base.getTable("Orders");
let lookupRangeRecords = await lookupTable.selectRecordsAsync();

    for (let rangeRecord of lookupRangeRecords.records) {

Wrapped everything in If Statements

if( x !== null)
