JavaScript code to locate the most pertinent strings within an array based on a specific substring

I'm working with a large array containing names of people, such as:

let names = [
   "John Brown", 
   "Tristan Black", 
   "Carl Jobbs", 
   "Aidan Burrows", 
   "Taylor Joe"
];

When given an input, I want to return the top 5 most relevant results from this array. Currently, I am using a loop to check for names like this:

if(name.toLowerCase().includes(input.toLowerCase()))
{
    console.log("Found match : " + name);
}

However, this method is not effective in finding the most relevant search results as it matches any name with the input in it.

My ideal solution would be to iterate through the array of names and identify the top 5 results that are most similar to the input. How can I achieve this?

Answer №1

Based on my understanding of your query, the following function should meet your requirements:

function searchByName(input, nameList) {
  
  return nameList.filter(name => (name.toLowerCase().includes(input.toLowerCase())))
}

let names = ["Sarah Smith", "Michael Johnson", "Emily White", "Adam Brown", "Olivia Green"];

console.log('Matches for Emm:', searchByName('Emm', names))
console.log('Matches for John:', searchByName('John', names))
console.log('Matches for Mic:', searchByName('Mic', names))
