String rewriting in JavaScript

Here is the JavaScript code.

textLineList1 = [
	"var data1 = \"[DATA]\";",
	"var pat1 = \"[PAT]\";",
	"",
	"console.log(\"data1=[\" + data1 + \"]\");",
	"console.log(\"pat1=[\" + pat1+ \"]\");",
	"var reg1 = new RegExp(pat1);",
	"var match1 = reg1.exec(data1);",
	"if (match1) {",
	"\tvar n1 = match1.length;",
	"\tfor (var i1=1; i1<n1; i1++) {",
	"\t\tvar text2 = match1[i1];",
	"\t\tif (text2) {",
	"\t\t\tconsole.log(\"\\tmatch \" + i1 + \" is [\" + text2 + \"]\");",
	"\t\t\t}",
	"\t\t}",
	"\t}",
	];

envPat1 = "(.*?)(\\[([A-Z0-9]+)\\])(.*)";
envReg1 = new RegExp(envPat1);

function envDo1(text1, envDict1) {
	var text2 = "";
	while (true) {
		var match1 = envReg1.exec(text1);
		if (! match1) {
			return text2 + text1;
			}
		var prefix1 = match1[1];
		var name1 = match1[3];
		var suffix1 = match1[4];
		text2 += prefix1;
		var text3 = envDict1[name1];
		text2 += text3;
		text1 = suffix1;
		}
	return text2;
	}

function codeTest1() {
	var pattern1 = "(\\d+)\\-(\\d+)";
	var data1 = "12345-6789";
	var envDict1 = {};
	envDict1["PAT"] = pattern1;
	envDict1["DATA"] = data1.replace("\\", "\\\\");
	var list1 = textLineList1;
	var n1 = list1.length;
	for (var i1=0; i1<n1; i1++) {
		var text1 = envDo1(list1[i1],envDict1);
		console.log(text1+"\n");
		}
	}

codeTest1();

Here is the output of the JavaScript code.

var data1 = "12345-6789";

var pat1 = "(\d+)\-(\d+)";



console.log("data1=[" + data1 + "]");

console.log("pat1=[" + pat1+ "]");

var reg1 = new RegExp(pat1);

var match1 = reg1.exec(data1);

if (match1) {

	var n1 = match1.length;

	for (var i1=1; i1<n1; i1++) {

		var text2 = match1[i1];

		if (text2) {

			console.log("\tmatch " + i1 + " is [" + text2 + "]");

			}

		}

	}

Here is the JavaScript code.

var data1 = "12345-6789";
var pat1 = "(\\d+)\\-(\\d+)";

console.log("data1=[" + data1 + "]");
console.log("pat1=[" + pat1+ "]");
var reg1 = new RegExp(pat1);
var match1 = reg1.exec(data1);
if (match1) {
	var n1 = match1.length;
	for (var i1=1; i1<n1; i1++) {
		var text2 = match1[i1];
		if (text2) {
			console.log("\tmatch " + i1 + " is [" + text2 + "]");
			}
		}
	}

Here is the output of the JavaScript code.

data1=[12345-6789]
pat1=[(\d+)\-(\d+)]
	match 1 is [12345]
	match 2 is [6789]
