Updating product stock status programmatically in Magento 2.3.x

Question

I have been facing an issue lately, I want to allow some products to be added to cart and ordered (programmatically) even if they're Out of Stock, I have succeeded in updating both is_in_stock and stock_status but the product stock isn't updating right away, the changes only reflect when the page is reloaded.

This is the code I used to update and edit stock data

$product = $this->_productRepository->getById($childProduct->getId());

$product->setStockData([
           'stock_id' => 1,
           'use_config_manage_stock' => 0,
           'manage_stock' => 0,
           'is_in_stock' => 1
          ]);

$product->setQuantityAndStockStatus([
           'stock_id' => 1,
           'use_config_manage_stock' => 0,
           'manage_stock' => 0,
           'is_in_stock' => 1
          ]);

$product->setIsSuperMode(true);

$product->save();

die(var_dump($product->getIsSalable())); //Returns FALSE, however after refresh it returns TRUE. 

Any help is appreciated!

You can use below sample code

$product->setStockData(['qty' => $yourQty, 'is_in_stock' => 1,'manage_stock'=>$your_manage_stock(Not Zero)]);
$product->setQuantityAndStockStatus(['qty' => $yourQty, 'is_in_stock' => 1,'manage_stock'=>$your_manage_stock(Not Zero)]);
$product->save();
