Match the part of a string in the array using JavaScript

I have a single dimensional array with the below format,

let e = ["CGST:20", "SGST:20", "IGST:20", "CESS:20", "GSTIncentive:20", "GSTPCT:20"].map(i=>i.trim());

And want to match the specific string in the array, say for example, match the part of the string "IGST" in the "IGST:20".

I have tried in the below way, but it always matching the first key in the array,

if(/^IGST:/.test(e)){
  console.log("matched")
} else {
  console.log("Not matched")
}

If your goal is to find out if that regular expression matches any entry in the array, you can use the some function for that:

if (e.some(entry => /^IGST:/.test(entry)) {
    console.log("matched")
} else {
    console.log("Not matched")
}

If you want to find the matching entry, use find instead. If you want its index, use findIndex.
