analyzing a string by considering various separators

I'm working on breaking down a string to:

  • Remove the initial word "lunch"
  • Separate the days of the week from their corresponding food items

The input is received as a string in this format:

var s = 'lunch monday: chicken and waffles, tuesday: mac and cheese, wednesday: salad';

My objective is to split it into:

[monday, chicken and waffles, tuesday, mac and cheese, wednesday, salad]

I'm currently using 

s = s.split(' ').splice(1, s.length-1).join(' ').split(':');

With this process, I get:

["monday", " chicken and waffles, tuesday", " mac and cheese, wednesday", " salad"]

However, it only splits at the :, leaving the , intact. I attempted using regex split(":|\\,"); to split based on either : or ,, but that didn't work.

Any suggestions?

Answer №1

If you are looking to split on both of those characters, simply adjust your Regular Expression like this:

// Add the 'g' flag to match all instances of either character
input.split(/[:,]/g);

To achieve what you want, you can combine these methods using the replace() and split() functions:

// Trim any leading "lunch " and then split based on specified characters
var output = input.replace(/^lunch /,'').split(/[:,]/g);

For example:

var input = 'lunch monday: chicken and waffles, tuesday: mac and cheese, wednesday: salad';
var output = input.replace(/^lunch /,'')
                  .split(/[:,]/g)
                  .filter(function(x){ return x.length > 0;});
alert(output);

Answer №2

Check out this solution utilizing the replace() and split() methods

var str = 'breakfast monday: pancakes, tuesday: eggs, wednesday: cereal';

str = str.replace('breakfast ', '');
str = str.replace(/:(\ )/g, ',');
str = str.split(',');
console.log(str);

Resulting Output:

["monday", "pancakes", " tuesday", "eggs", " wednesday", "cereal"]

Answer №3

I'm not completely sure if I grasp the aim you're trying to achieve. Is it perhaps

 let message = 'breakfast monday: pancakes and syrup, tuesday: eggs and bacon, wednesday: oatmeal';

let arrayMessage = message.split(/:|,/);

arrayMessage.forEach(function(item){
    document.write(item + "<br>")
});
