• 1 ["ITEM_1", "ITEM_2", "ITEM_3"].map(e => e.replace('ITEM_', '')) – Nenad Vracar Commented Apr 2, 2017 at 19:29
• You can use regex to extract number developer.mozilla/fr/docs/Web/JavaScript/Guide/… – Incognito Commented Apr 2, 2017 at 19:29
• @qatari, do you want to modify the initial array? – RomanPerekhrest Commented Apr 2, 2017 at 20:14

Sorted by: Reset to default 3

or:

var arr = ["ITEM_1", "ITEM_2", "ITEM_3"].map(function(item){
return item.split('_')[1];
});

or:

var arr = ["ITEM_1", "ITEM_2", "ITEM_3"].map(function(item){
return item.replace('ITEM_', '');
});

You could do:

console.log(
  ["ITEM_1", "ITEM_2", "ITEM_3"].join().match(/\d+/g)
)
