I have written a program for Truffle console. My code accesses the string and should return statements related to Solidity send and transfer. When I am testing each line of Solidity SC as shown below, I am getting correct result but when I am testing using the whole code stored in the "string" variable, the false condition is not working or there is some other problem due to which I am getting all the lines of Solidity code instead of just send and transfer statements. For example:

Str[ctr] = "bool sent = _to.send(msg.value);".includes(keyWords[keyWordCtr])//true 

My complete code is :

var assert = require('assert');
const path = require("path");

module.exports = async function(callback) 
   try { 

string = `contract SendEther {
    function sendViaTransfer(address payable _to) public payable {

    function sendViaSend(address payable _to) public payable {
        bool sent = _to.send(msg.value);
        require(sent, "Failed to send Ether");}

    function sendViaCall(address payable _to) public payable {
        (bool sent, bytes memory data) = _to.call{value: msg.value}("");
        require(sent, "Failed to send Ether");}}`
const Str=[];
let ctr=0;
lines = string.split(/\r\n|\n/);
const keyWords = new Array( ".send(", "transfer(");
for (let keyWordCtr = 0; keyWordCtr <1; ++keyWordCtr){
   for(let line = 0; line < lines.length-1; line++){
      if (lines[line].includes(keyWords[keyWordCtr]) == false)//Note replacing search by includes not working
      Str[ctr] = (lines[line].includes(keyWords[keyWordCtr])? lines.toString() : false);
for(let i = 0; i< Str.length; i++)
       catch (error) {

When I am executing the program, I am getting the whole code, otherwise, I found that only two following statements are returning true values:

bool sent = _to.send(msg.value);

Somebody please guide me how to fix my code so that it returns only the above two statements of Solidity program. Right now it is returning the entire Solidity code.

I have solved this problem. I had a problem with the string:

Str[ctr] = (lines[line].includes(keyWords[keyWordCtr])? lines.toString() : false);

When I changed it to:

Str[ctr] = (lines[line].includes(keyWords[keyWordCtr])? lines[line].toString() : false);

My program is working.
