(javascript) If you had a string that was a word with a number at the end. How would you add a space-CodePudding

For example:

let word = 'Winter4000'

const seperate = (word) => {
  ...
}

seperate(word) // output: Winter 4000

The word can be random and the number is always at the end.

Ian's answer works for most integers, but for decimals or numbers with commas (like 1,000,000), you'll want an expression like

word.split(/([0-9.,] )/).join(" ");

so it doesn't put an extra space when it runs into a decimal point or comma.

Writing this as a function,

let word = 'Winter4,000.000';

const seperate = (input_word) => {
    return input_word.split(/([0-9.,] )/).join(" ");
}

console.log(seperate(word));

CodePudding user response：

let word = 'Winter4000'
const seperate = word.split(/([0-9] )/).join(" ")

split it using regex pattern looking for numbers, then join it back together with a space added

const word = 'Winter4000';
const result = word.match(/[^\d] /)   ' '   word.match(/[\d] /);
