How can I detect an emoji character from ACSII character?-CodePudding

Given a string that can only be a single ASCII character or an emoji char sequence. How can I tell one from another?

The idea is to separate emojis from plain text, by the spec if you are given a string of chars mixed with emojis then by doing for (..of) you can get substrings of ASCII chars and Emojis sparately

const text = 'ascii and emojis mixed'
for (const char of text) {
    // ... here, a char would be either an ASCII char or an emoji sequence string
    if (seeIfAscii(char)) {
       console.log('ASCII', char);
    } else {
       console.log('Emoji', char);
    }
}

function seeIfAscii(char) {
   // what comes here? <--- QUESTION!!!
}

As to why, I need to clump ASCII chars together and keep emojis one by one separate.

You can use String.charCodeAt to get the unicode number of the character:

> x = "abc
