I want to do it like I give a list of words and a meaning to them e.x.:

'szia' = 'hello' 'mizu' = 'whats up'

and then I have a string that goes like this: var string = "szia mizu". How can I replace the words there from the list?

  • Does this answer your question? [How to replace all occurrences of a string in JavaScript](https://stackoverflow.com/questions/1144783/how-to-replace-all-occurrences-of-a-string-in-javascript) – Rafał Figura Apr 12 '22 at 19:07

  • you could have a dictionary holding the translations. then you can use split method on your string and for each word look up the translation in the dictionary. – coglialoro Apr 12 '22 at 19:11

let sentence = "szia mizu";

const traduction= {
  "hello": ['szia'],
  "whats up": ['mizu']
};

function fileAndReplace(sentence, traduction) {
  let newSentence = sentence;
    
  Object.keys(traduction).forEach(key => {
      const checktrad = new RegExp(traduction[key].join('|'),'gi');
      newSentence = newSentence.replace(checktrad , key);
  })
     
  return newSentence;
}

console.log(fileAndReplace(sentence, traduction))

you need to iterate through all the keys in your dictionary and create a regex for that specific key. Then you just feed that regex to the .replace() with the synonym regex and the key you want to replace it with.

You can archive this with js replace() function:

const needles = {
  szia: "hello",
  mizu: "whats up"
};

let str = "szia mizu";

Object.keys(needles).forEach(n => {
  str = str.replace(n, needles[n]);  
})

console.log(str)
