Given an array like the below code :
let words = ['bring','constant','bath','spring','splashing']
How do I print all string characters with ing characters from the words array ?
You need to use endsWith method to check if the word ends with a specific value.
let words = ['bring','constant','bath','spring','splashing']
const result = words.filter(w => w.endsWith('ing'))
result.forEach(w => console.log(w))You also can use regular expressions with dollar sign $ means end with.
let words = ['bring','constant','bath','spring','splashing']
const result = words.filter(w => /(ing)$/.test(w))
result.forEach(w => console.log(w))As author want to check if ing exist in the middle of the word or not. In that case you can just use normal regex with String.match() method without $ sign at end.
Live Demo :
let words = ['bring','constant','bath','spring','splashing', 'tingtong'];
const res = words.filter(word => word.match(/ing/ig));
console.log(res);Or you can also achieve that by using .includes() method.

let words = ['bring','constant','bath','spring','splashing', 'tingtong'];
const res = words.filter(word => word.includes('ing'));
