Array Clear out in Javascript Lightning Web Component

Question

In an Array multiple values(List) are coming and i need to clear out the particular list on the basis of a boolean value For example

In Child Component two values are getting passed as below:

<c-child = warninglist = {Alist}></child>


           this.Alist.push({
                            name: 'CCI',
                            variant: 'Warning',
                            aMessage: 'crufs',
                            cbut: false,
                            dOtric: true,
                            mInfo: 'trsdt'
                        });

           this.Alist.push({
                            name: 'CCI',
                            variant: 'Warning',
                            aMessage: 'crufs',
                            cbut: false,
                            dOtric: false,
                            migf: 'trsdt'
                        });


   In child Component Alist is being received in the warninglist

    In Child component how can i clear only the particular value if dOtric is false?? can anyone help me on this.

In the child component, you can use the filter method to get value with dOtric is false. Playground example.

    warninglistFiltered = [];

    @api
    get warninglist() {
        return this.informationgirl;
    }

    set warninglist(value) { 
        this.warninglistFiltered = value.filter(warning => (warning.dOtric === false));       
    }
