let xhr = new Ajax();
// or

// offer many properties and methods that you can control Ajax instance
`

properties


`ts
static defaults: {
[key: string]: string | boolean | number;
};
readonly xhr: XMLHttpRequest;
readonly readyState: string;
readonly status: number;
readonly statusMessage: string;
readonly response: any;
body: ArrayBuffer | Blob | string | {
[key: string]: any
} | FormData | HTMLFormElement;
method: string;
url: string;
responseType: string;
charset: string;
async: boolean;
headers: {
[key: string]: string
};
length: number;
events: {
[key: string]: (event: Event) => void;
};
timeout: number;
query: string;
queryUsed: boolean;
bodyUsed: boolean;
options: (ops: object) => void;
getResponseHeadaer: (key: string) => string;
on: (ev: string, fn: (event: Event) => void) => void;
abort: () => void;
fetch: () => Promise;
`

methods

`ts
// shortname of above properties setting
options: (ops: object) => void;
getResponseHeadaer: (key: string) => string;
on: (ev: string, fn: (event: Event) => void) => void;
abort: () => void;
fetch: () => Promise;
`

Attention please, if you want to use get method, using query instead of body

`js
// you want to get some data from http://www.example.com?name=DoubleDimos&age=22

// codes below will not work correct
async getData() {
let ajax = new Ajax('get', 'http://www.example.com', true);
ajax.body = {
name: 'Double Dimos',
age: 22
};
return await ajax.fetch();
}

// using this instead

async getData() {
let ajax = new Ajax('get', 'http://www.example.com', true);
ajax.query = {
name: 'Double Dimos',
age: 22
};
return await ajax.fetch();
}
