What is the best way to retrieve an accurately matched array?

I am working on a function that analyzes a string of DNA and should return an accurately matched DNA array. Here is the code snippet I have experimented with:

function checkDNA(dna) {
   var dnaarr = [];


    for(var i = 0; i < dna.length; i++) {
         var str = [];
str.push(dna[i]); //adding current dna letter to str array
      if(dna[i].indexOf('') === 0) {
        var a = str.push('sd');
      }
      if(dna[i].indexOf('GGC') === 0) {
        var b = str.push("GC", "GC", "CG");
      }
      if(dna[i].indexOf('gat') === 0) {
        var c = str.push("GC", "AT", "TA");
      }
      if(dna[i].indexOf('PGYYYHVB') === 0) {
        var d = str.push('GC');
      }
dnaarr.push(str); //adding the str array to the main dnaarr array
    }


    return dnaarr;
}

To decipher the values of each character in a string, consider representing nucleobases as objects and extracting the characters one by one.

If there are unknown characters, they will be filtered out at a later stage.

function pair(string) {
    var nucleobases = { G: 'C', C: 'G', T: 'A', A: 'T' };

    return Array
        .from(string.toUpperCase(), s => s in nucleobases && s + nucleobases[s])
        .filter(Boolean);
}

console.log(pair('GTTC'));

You're considering this from the wrong perspective. It's important to properly log those values.

Think about it in terms of a database approach.

Here's an example for you to consider:

If you want to add DNA sequences, you can follow these steps:

1. Define an object called dnaRules.
2. Implement a function called register that takes a key as input.
3. Inside the register function:
   - Create a new item object.
   - Check if the key already exists in dnaRules, return it if so.
   - If the key doesn't exist:
      - Initialize an empty array at the key index.
      - Add an equal method to the item object which sets a data value.
      - Assign the item to dnaRules under the provided key.
4. Register specific DNA sequences using the register function and defining their equivalent sequences.
5. To search for a DNA sequence, use the search function:
   - Compare the input value with the keys in dnaRules.
   - Return the corresponding DNA sequence if a match is found.
6. Retrieve the search result and display the associated data.

Remember, you can also modify the stored DNA sequences by using the equal method."
