Here you can use regex also :

let arr = ["generate-image-scanID-60", "generate-image-scanID-40"];

let t = arr.map((x) => +x.match(/^.*-(\d+)/)[1]);

console.log(t);

You can split the string and get last element and parse int

const raw = ['generate-image-scanID-60', 'generate-image-scanID-4']

const result = raw.map(str => parseInt(str.split('-').at(-1), 10))

console.log(result)

We can combine String.split() and Array.at() to do it

let datas =['generate-image-scanID-60','generate-image-scanID-4']
const getData = v => v.split('-').at(-1)

datas.forEach(d => {
  console.log(getData(d))
})
