how to print all values from an array containing a given string value (JavaScript)-CodePudding

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 ?

CodePudding user response：

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))

CodePudding user response：

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.

Live Demo :

let words = ['bring','constant','bath','spring','splashing', 'tingtong'];

const res = words.filter(word => word.includes('ing'));

console.log(res);
