How can I overite core helper?

Hi all, I’m working with magento2 and trying to add multiple personable product functionality to VSF cart.
I had success by changing one of the helper in the cart core module. My question is how and what is the best way to overite the core helper? helper is productsEquals.ts

Let me replay myslef :slight_smile: Maybe help someone.

copy core module in src/modules and do your chages
in src/client.ts change core module dir to your custom module dir (src/yourModule) thats it
