Declaring array of objects

Question

I have a variable which is an array and I want every element of the array to act as an object by default. To achieve this, I can do something like this in my code.

Answer 1

The below code from my project maybe it good for you

  reCalculateDetailSummary(updateMode: boolean) {

    var summaryList: any = [];
    var list: any;
    if (updateMode) { list = this.state.pageParams.data.chargeDefinitionList }
    else {
        list = this.state.chargeDefinitionList;
    }

    list.forEach((item: any) => {
        if (summaryList == null || summaryList.length == 0) {
            var obj = {
                chargeClassification: item.classfication,
                totalChargeAmount: item.chargeAmount
            };
            summaryList.push(obj);

        } else {
            if (summaryList.find((x: any) => x.chargeClassification == item.classfication)) {
                summaryList.find((x: any) => x.chargeClassification == item.classfication)
                    .totalChargeAmount += item.chargeAmount;
            }
        }
    });

    if (summaryList != null && summaryList.length != 0) {
        summaryList.push({
            chargeClassification: 'Total',
            totalChargeAmount: summaryList.reduce((a: any, b: any) => a + b).totalChargeAmount
        })
    }

    this.setState({ detailSummaryList: summaryList });
}
