How to get data with axios from all api pages?

Question

JavaScript

What am I doing wrong? I want to get data from all pages in api. I think the while is the problem, but I don't know how to run the page loop any other way!

getCustomers: function() {
                let url = '/crm/customer/';
                return axios.get(url).then((response) => {
                   this.customers = response.data.results;
                   if (this.customers.length === 100) {
                        let i = 2;
                        axios.get('/crm/customer/?page=' + i).then((response) => {
                          this.c = response.data.results;
                          i += 1;
                          for (let item of this.c.values()) {
                              this.customers.push(item);
                          }
                          while (this.c.length === 100) {
                              axios.get('/crm/customer/?page=' + i).then((response) => {
                                this.c = response.data.results;
                                i += 1;
                                for (let item of this.c.values()) {
                                  this.customers.push(item);
                                }
                              }).catch( error => {}).finally(() => (global_waiting_stop()));
                          }
                        }).catch( error => {}).finally(() => (global_waiting_stop()));
                   }
                 }).catch( error => {}).finally(() => (global_waiting_stop()));
            },

1) Stopped working what?
Guess:
2) "axios await async habr qna" in the search engine, there are links here on how then works . Asynchrony. The command seems to be completed, and the value will be later.
Promises annoy me a little))), but it's interesting to puzzle with them.
