omit

omit is a utility function that accepts a Signal<object> and an array of properties to omit. It returns a Signal<object> with the passed in properties omitted.

Usage

interface MyCmpOptions extends Partial<NgtThreeElements['ngt-group']> {
    foo: string;
    bar: number;
}

const defaultOptions: MyCmpOptions = {
    foo: 'foo',
    bar: 1,
}

@Component({
    template: `
        <ngt-group [parameters]="parameters()">
        </ngt-group>
    `
})
export class MyCmp {
    options = input(defaultOptions, { transform: mergeInputs(defaultOptions) });

    parameters = omit(this.options, ['foo', 'bar']);
}

Equality function

By default, omit uses shallow check for objects and array values when an array of keys is passed in. You can pass a custom equality function in via the 3rd argument equal

export class MyCmp {
    options = input(defaultOptions, { transform: mergeInputs(defaultOptions) });

    parameters = omit(
        this.options,
        ['foo', 'bar'],
        (a, b) => a.name !== b.name
    );
}
