To keep the promise chain going, you can't use setTimeout() the way you did because you aren't returning a promise from the .then() handler - you're returning it from the setTimeout() callback which does you no good.
Instead, you can make a simple little delay function like this:
function delay(t, v) {
return new Promise(function(resolve) {
setTimeout(resolve.bind(null, v), t)
});
}
And, then use it like this:
getLinks('links.txt').then(function(links){
let all_links = (JSON.parse(links));
globalObj=all_links;
return getLinks(globalObj["one"]+".txt");
}).then(function(topic){
writeToBody(topic);
// return a promise here that will be chained to prior promise
return delay(1000).then(function() {
return getLinks(globalObj["two"]+".txt");
});
});
Here you're returning a promise from the .then() handler and thus it is chained appropriately.
You can also add a delay method to the Promise object and then directly use a .delay(x) method on your promises like this:
function delay(t, v) {_x000D_
return new Promise(function(resolve) { _x000D_
setTimeout(resolve.bind(null, v), t)_x000D_
});_x000D_
}_x000D_
_x000D_
Promise.prototype.delay = function(t) {_x000D_
return this.then(function(v) {_x000D_
return delay(t, v);_x000D_
});_x000D_
}_x000D_
_x000D_
_x000D_
Promise.resolve("hello").delay(500).then(function(v) {_x000D_
console.log(v);_x000D_
});Or, use the Bluebird promise library which already has the .delay() method built-in.
