For example, when given "hello world", I want [ "he", "ll", "o ", "wo", "rl", "d" ]
returned.
I've tried "hello world".split(/../g)
, but it didn't work, I just get empty strings:
console.log("hello world".split(/../g));
I've also tried using a capture group which makes me closer to the goal:
console.log("hello world".split(/(..)/g));
The only real solution I can think of here is to prune out the empty values with something like this:
let arr = "hello world".split(/(..)/g);
for (let i = 0; i < arr.length; i++) {
if (arr[i] === "") arr.splice(i, 1);
}
console.log(arr);
Even though this works, it's a lot to read. Is there a possible way to do this in the split function?
let str = "hello world";
let arr = [];
for (let i = 0; i < str.length; i++) {
arr.push(str[i++] + (str[i] || ''));
}
console.log(arr);
You can use .match()
to split a string into two characters:
var str = 'hello world';
console.log(str.match(/.{1,2}/g));
You can also increase the number of splitting by editing {1,2}
into numbers like 3
, 4
, and 5
as in the example:
3 characters split:
var str = 'hello world';
console.log(str.match(/.{1,3}/g));
4 characters split:
var str = 'hello world';
console.log(str.match(/.{1,4}/g));
