January 24, 2025 - The .filter() function takes a predicate – a function that returns true or false. In .map() we get the return value of the mapper function; with .filter() we use the return value of the predicate to determine if the value will appear in the new result array.

February 6, 2023Filter pipe for multiple fields with nested array
you need to iterate over the listOfItems array from within the filter function - find will do it for you. i can't remember the exact syntax for pipes off the top of my head but here's a function that should do what you want:
specialSearch(obj) {
myArray.filter(entry => {
return entry.name === obj.name && entry.listOfItems.find(item => item.description === obj.description);
});
}so we only allow entries in the top-level array that both have a name matching the name we input, but we must also find an item in listOfItems that has a description matching the description we input.

October 10, 2016A slightly faster array filter
I see that you have moved away from searching for 'w', but I was wondering if you were only focused only on the 'Where' capabilities? On my system (PowerShell 5.1) this seems to go faster than your 'Where' and 'Class' examples measure-command { foreach ($i in 0..1kb) { foreach($item in $files){if([char]$item.Name[0] -match 'w') {$item}} } } | Select-Object -ExpandProperty TotalMilliseconds Your example times on my system (far fewer 'w' files than you): 303.2 265.6 My example 189.2 More on reddit.com
