Replace text to make markdown or formatting

March 28, 2023

I want to replace *hello* to hello how will i be able to do that? and the same but with other prefixes

let content = '*Hello*, my **friend** how are you?'

      function formatString(content) {
        let step1 = content.split(" ").join(" ").replaceAll("\n\n", "</br></br>");
        //replace
      }
      formatString(content)//should return '<i>Hello</i>, my <b>friend</b> how are you?'

I tried using regex but I was only able to replace *string* to string only instead of string

>Solution :

the replaceAll method with the regex /*(.?)*/g to replace all occurrences of string with string, and /**(.?)**/g to replace all occurrences of string with string. The g flag makes sure that all occurrences are replaced, not just the first one.

let content = '*Hello*, my **friend** how are you?'

function formatString(content) {
  let step1 = content.split(" ").join(" ").replaceAll("\n\n", "</br></br>");
  let step2 = step1.replaceAll(/\*(.*?)\*/g, "<i>$1</i>");
  let step3 = step2.replaceAll(/\*\*(.*?)\*\*/g, "<b>$1</b>");
  return step3;
}

console.log(formatString(content))
