Convert the output of for loop of JSON in string

Question

How can I combine the output data and make it a string, from a for loop in Javascript.

Here's my snippet.

for (let index = 0; index < routes.length; index++) {
     let element = routes[index];
     meSpeak.speak(element.narrative, speakConfig);
}

It results,

word1
word2
word3
word4

I want to make it as a one String only. like this

word1 word2 word3 word4

routes.forEach(element => meSpeak.speak(element.narrative, speakConfig).join(' '); should work — Adi Ulici

Just use join()

const routes = [{'narrative':'word 1'},{'narrative':'word2'},
{'narrative':'word 3'},{'narrative':'word 4'}];
let out = []

routes.map((el)=>(out.push(el.narrative)));
res = out.join(' ');

You can try using array. I have sample codes here. Try to implement the logic in your problem

var apples = ["Apple1", "Apple2", "Apple3", "Apple4"];
fruits.toString();

The result will be like:

Apple1,Apple2,Apple3,Apple4

You could add the strings to a variable outside of the for loop and then "speak" the string when the for loop is done.

s = ""
for (let index = 0; index < routes.length; index++) {
     s += str(routes[index].narrative)
}
meSpeak.speak(s, speakConfig);
