Benchmark: _.replace(line, /\r\n|\n/, '') vs .indexOf('/n') #4

HTML Preparation code:

<!--your preparation HTML code goes here-->

Script Preparation code:

// 1. 짧은 문자열 (일반적인 코드, 수량 등)
var shortStr = "EC_12345";
var shortStrWithNewline = '"EC_12345\nTEST"'; // 따옴표로 감싸진 형태 가정

// 2. 긴 문자열 (장문형식, 적요 등) - 약 10KB
var longStr = "A".repeat(10000); 
var longStrWithNewline = '"' + longStr + '\nEnd"';

// 3. 테스트할 정규식 (ConvertRowToDmcSvc.ts에 있는 것)
var targetRegex = /[\s\S]*\n[\s\S]*/g;

// 4. replaceFunc (간소화)
function replaceFunc(data) {
    return data.slice(1, -1).replace(/""/g, '"');
}

Tests:

_.replace
// 기존 방식: 긴 문자열 전체 스캔 발생 longStr.replace(targetRegex, replaceFunc);
.indexOf(/n)
// 개선 방식: indexOf는 매우 빠르므로 즉시 통과 if (longStr.indexOf('\n') > -1) { longStr.replace(targetRegex, replaceFunc); } else { var result = longStr; }
