Check if there is white space between letters in a string - IGNORE SPACE, TAB AND ENTER AT THE END OF THE WORD

Question

I have searched and found ways to check for ALL whitespace existence between letters in a string but what about if the string contains a space, tab or enter at the end?

For example:

let str="John ";
console.log(str.includes(' '));

The above console.log will return true because there is a space at the end, however that is not relevant for me. I only wanted to check for:

let str="J o h n";

How to achieve this with Javascript ( and totally ignore space check at the end)?

I think OP does not want to trim(), just remove in between whitespaces — Tushar Gupta, Mar 10 '22 at 15:04
yes that is right, I want to check if there are spaces between letters but ignore the space at the end. — RandomDeveloper, Mar 10 '22 at 15:08

`console.log(str.trim().includes(' '));` will do exactly what you want — mplungjan, Mar 10 '22 at 15:13

function splitCheck(str){ for(let o of str.trim().split(' ')){ if( !o) return false }; return true; } tou can try this — ShobiDobi, Mar 10 '22 at 15:18

If I understand your question correctly, this is what you want to achieve:

let str="John ";
console.log(/\s$/.test(str));

this returns true however it should return false because I don't care about space at the end – RandomDeveloper Mar 10 '22 at 15:10
