Angular - Filter array based on two property values

Question

I'm having some problem in deleting the array items based on two property values..

If we compare to classic Sql delete command, What I have to do is something like this:

DELETE oImages WHERE idOffertRow = 1 and idProductImage = 2

I don't know how to convert this sql example command in typescript.

This is that I'm ttrying to do but it doesn't work:

this.oImages = this.oImages.filter(function (obj) {
          return obj.idOffertRow !== oRow.idOffertRow && obj.idProductImage !== i.idProductImage;
        });

Thanks to support

this.oImages = this.oImages.filter(obj => idOffertRow !== 1 || idProductImage !== 2);

Filter is about keeping, not deleting. So invert your condition. With De Morgan's law, it gives

A . B ---> !A + !B
