如何将句子数组转换为单词数组？ (JS)

Question

I currently have an Array with several sentences and I want to change the Array so each word is an item.

Right now the console log of the array looks like this:

[
'Lorem ipsum dolor sit amet, consectetur adipiscing elit',
'Sed faucibus mattis odio, eu rhoncus ante porttitor sit amet',
'Pellentesque ac elementum diam',
'Ut sagittis faucibus ante, et egestas erat maximus vitae'
]

I want it to be like:

['Lorem', 'ipsum', 'dolor', ...etc]

I tried using the split() method, but then it creates several arrays inside the original array with the split words of each sentence. What's the best way to do it?

Answer 1

After split, you have a multilevel array. What you would want to do is flatten your array.

let ans = q.map((a)=>{
  return a.split(' ');
}).flat();

As pointed out by @Reyno, this can be achieved using flatMap() too:

let ans = q.flatMap(a => a.split(' '));

Answer 2

You can easily achieve this result using flatMap

 const arr = [ "Lorem ipsum dolor sit amet, consectetur adipiscing elit", "Sed faucibus mattis odio, eu rhoncus ante porttitor sit amet", "Pellentesque ac elementum diam", "Ut sagittis faucibus ante, et egestas erat maximus vitae", ]; const result = arr.flatMap((str) => str.split(" ")); console.log(result);

Answer 3

 const arr = [ 'Lorem ipsum dolor sit amet, consectetur adipiscing elit', 'Sed faucibus mattis odio, eu rhoncus ante porttitor sit amet', 'Pellentesque ac elementum diam', 'Ut sagittis faucibus ante, et egestas erat maximus vitae' ]; const out = arr.reduce((a, b) => { return a.concat(b.split(" ")); }, []); console.log(out);
