replace handler en masse

September 22, 2022

Hello, How to work with replace in bulk
I want to replace in bulk, and not to take up too much code
Look at how I do it:

    const t1 = service.replace[
        'SERVICE=1', 'test1',
        'SERVICE=3', 'test2',
        'SERVICE=2', 'test3'
    ]
    // const t = service
    // .replace('SERVICE=1', 'test1')
    // .replace('SERVICE=2', 'test3')
    // .replace('SERVICE=3', 'test2')

>Solution :

You can create a little function. Please note it replaces only first occurrence of each string. Also, pay attention of passing the longer strings first, so to prevent side effects of replacing strings that contained in other strings.

function replacer(str, data) {
  if (typeof data === 'object' && str) {
    for (var key in data) {
      var value = data[key];
      str = str.replace(key, value);
    }
  }
  return str;
}

console.log(replacer("goodbye galaxy", {
  "goodbye": "hello",
  "galaxy": "world"
}))

// stay tuned for a prototype of String
String.prototype.replacer = function(data) {
  return replacer(this, data);
};
console.log("goodbye galaxy".replacer({
  "goodbye": "hello",
  "galaxy": "world"
}))
