I would like to loop through and array and then get the last two letters from each string and create a new array with them?
my current array is
myArray = [Qe3,Ke4,Qe5,Je6]
I would like to end up with this
newArray = [e3,e4,e5,e6]
this is for www.chessonline.app
you need to loop over the array and cut first character !
const myArray = ['Qe3','Ke4','Qe5','Je6']
const newArr = myArray.map((el) => el.substring(1));
Use slice
const newArray = myArray.map(str => str.slice(-2)); // Use map() to apply a function to each element of the array
// The function uses slice() to return the last two characters of each string
console.log(newArray); // ['e3', 'e4', 'e5', 'e6']
We can use a slice here:
var myArray = ["Qe3", "Ke4", "Qe5", "Je6"];
var output = myArray.map(x => x.slice(-2));
console.log(output);
