I have array in txt file and read this with
fs.readFileSync("./input.txt")
When i wrap it in console.log i get(since it is written in the file itself):
1 2 3
100 5000
I would have the array:
['1','2','3','100','5000']
Placement of the array in the input file should not change. Suggest how to do it, please.
You can use regex to split words: \w+
let a = ` 1 2 3
100 5000 `;
console.log(a.match(/\w+/g))To read your file and split it:
fs.readFileSync("./input.txt").match(/\w+/g)
One way, load it then, split by lines, then on each line split by space then flatten it, then filter out empty values.
let str = `1 2 3
100 5000 0`; // added 0 to show filter(Boolean) wont remove
console.log(str.split('\n').map(v => v.split(' ')).flat().filter(Boolean))Result:
[
"1",
"2",
"3",
"100",
"5000",
"0"
]
You could split the string by a space, then filter out the falsy items in the resulting array.
const input = ` 1 2 3
100 5000 `;
let res = input.split(" ").filter(e => e.trim())
console.log(res)
