Reading the share point list in SPFx – ForEach does not work

I do not know how to read the data from the Sharepoint list in SPFx one by one.

The JavaSript console returns an error: Not captured (promised) TypeError: item.forEach is not a function.

        ReadAllCountries () private: void {
var sel = document.getElementById ("visitstate");
this.context.spHttpClient.get (`$ {this.context.pageContext.web.absoluteUrl} / _api / web / lists / getbytitle (& # 39; TravelRequests_Countries & # 39;) / items? $ orderby = Title% 20desc & $ select = Title`, SPHttpClient .configurations.v1)
.then ((res: HttpClientResponse): Promise => {
returns res.json ();
})
.then ((item: any)): void => {
console.log (item)

var a: number = 0;
item.forEach (prd => {
var opt = document.createElement ("option");
opt.value = `$ {item[a].Title} `;
opt.text = `$ {item[a].Title} `;
sel.add (opt, sel.options[a])
a ++;
});

}, (error: any): void => {
console.log ('Loading user information failed with error:' + error);
});
}

My goal is to be able to read each line of the result one by one. Here, for example, only the title values.

The current output with console.log (item) is:
