Regex pattern for a string that ends with a space then a letter-CodePudding

I’m trying to make a regex pattern that would return true for when the string ends with a single letter.

Hello dear - false

Hello D - true

HelloD - false

Tried /\[^/sA-Z\]/ but of course that did not work :(

CodePudding user response：

You should be using the end ($) flag

/\s[A-Za-z]$/

CodePudding user response：

Ends in single letter

function isAllaz() {
  let a = ["Hello dear", "Hello D", "HelloD"];
  let o = a.map(s => {return `${s} - ${(s.match(/^.* [A-Za-z]$/))? 'true': 'false'}`});
  console.log(JSON.stringify(o));
}
