JavaScript Transferring from 1 dimensional array to 2dimensional array ?

[zak100]

Hi,
I have a problem in this line:

keyWordStr[[i],[ctr]] = files[i];//Added

File name is of 6 characters, how this transfer is taking place without a loop?

var assert = require('assert');
const path = require("path");
const fs = require("fs");
module.exports = async function(callback)
{
   try {
      var ctr =0;
      const keyWordStr = [[],[]];
      const files = new Array("A1.sol","A2.sol", "A3.sol");
     for (let i = 0; i < files.length; i++) {
        //console.log("Test" + i);
        const contractPath = path.resolve('/home/zulfi/Truffle_programs/search_opcode/','contracts',files[i]);
         //console.log(files[i]);
        keyWordStr[[i],[ctr]] = files[i];//Added
        ctr++;
     }
    console.log("keyWordStr = "+keyWordStr[0]);
    console.log("keyWordStr = "+keyWordStr[1]);
    console.log("keyWordStr = "+keyWordStr[2]);
}
catch (error) {
console.log(error)
}
callback()
}

Hi,



In the above code, I am getting the correct answer. The answer is:

$ truffle exec 2darrofstr.js

Using network 'development'.



keyWordStr = A1.sol

keyWordStr = A2.sol

keyWordStr = A3.sol

I have problem in understanding the line:



keyWordStr[,[ctr]] = files;//Added





Filename is of 6 characters. But these 6 characters are being stored in one character of keyWordStr[,[ctr]] i.e. keyWordStr[0][0], keyWordStr[1][1], keyWordStr[[2][2]. Somebody please guide me. Zulfi.
