spfx : Why it does't execute line by line

Where am I doing wrong?

So, I have created an spfx extension where I need to do few checks. All working fine except the code jumps from randomly. Now the execution of the code should get me D, A, B and C but it picks randomly, Sometimes C, D A B.

and thus am not able to build by business rules. The java script always gets first preferences.

For exampleL
const getListUrl: string = this.context.pageContext.web.absoluteUrl + "/_api/web/lists/GetByTitle("+BannerConfigurationList+")/items";
this.context.spHttpClient.get(getListUrl, SPHttpClient.configurations.v1)
.then((response: SPHttpClientResponse) => {
if (response.status === 200) {
response.json().then((responseJSON) => {
if (responseJSON != null && responseJSON.value != null) {
Get me D

const getListUrl: string = this.context.pageContext.web.absoluteUrl + "/_api/web/lists/GetByTitle("+BannerConfigurationList+")/items";
this.context.spHttpClient.get(getListUrl, SPHttpClient.configurations.v1)
.then((response: SPHttpClientResponse) => {
if (response.status === 200) {
response.json().then((responseJSON) => {
if (responseJSON != null && responseJSON.value != null) {
Get Me A

const getListUrl: string = this.context.pageContext.web.absoluteUrl + "/_api/web/lists/GetByTitle("+BannerConfigurationList+")/items";
this.context.spHttpClient.get(getListUrl, SPHttpClient.configurations.v1)
.then((response: SPHttpClientResponse) => {
if (response.status === 200) {
response.json().then((responseJSON) => {
if (responseJSON != null && responseJSON.value != null) {
Get Me B

const getListUrl: string = this.context.pageContext.web.absoluteUrl + "/_api/web/lists/GetByTitle("+BannerConfigurationList+")/items";
this.context.spHttpClient.get(getListUrl, SPHttpClient.configurations.v1)
.then((response: SPHttpClientResponse) => {
if (response.status === 200) {
response.json().then((responseJSON) => {
if (responseJSON != null && responseJSON.value != null) {

Get Me C

    These are all asynchronous requests, so the order of request return values may not be returned in the order of request. These requests can be set as synchronous requests, and the request results will be returned in order.

    1. async function
    2. Promise
