Google Sheets Concatenate Google Apps Script - google-apps-script

Question

I'm new to javascript and a novice coder. I have been trying to write a simple script for a Google Sheet to concatenate two columns of data into another column:
My script below runs fine but only produces Aaron Ward as line 1 of Desired Column C. I'm sure it is really simple what I am missing, but if anyone has a minute to help a rookie, I'd really appreciate it.
function concatenate() {
var sheet = SpreadsheetApp.getActiveSheet();
var data = sheet.getDataRange().getValues();
var lr = sheet.getLastRow()
var values1 = sheet.getSheetValues(1, 1, lr, 1);
var values2 = sheet.getSheetValues(1, 2, lr, 1);
var results = [];
for (var i = 0; i < lr; i++) {
results = [values1[i] + " " + values2[i]];
Logger.log(results);
sheet.getRange(1, 3, results.length).setValues([results]);
}
}

Answer 1

Why not using a formula? In C1 place the formula =JOIN(“ “,A1:B1) and drag it to the last row.

Answer 2

You're very close. In your for-loop, you need to push() the concatenated string into your results array. Then you can setValues(results) after the for-loop.
function concatenate() {
var sheet = SpreadsheetApp.getActiveSheet();
var data = sheet.getDataRange().getValues();
var lr = sheet.getLastRow()
var values1 = sheet.getSheetValues(1, 1, lr, 1);
var values2 = sheet.getSheetValues(1, 2, lr, 1);
var results = [];
for (var i = 0; i < lr; i++) {
results.push([values1[i] + " " + values2[i]]);
}
sheet.getRange(1, 3, results.length).setValues(results);
}

Answer 3

You can either use this
function conCat(){
var ss = SpreadsheetApp.getActiveSpreadsheet()
var ws = ss.getSheetByName("your sheet name")
var data = ws.getDataRange().getValues()
for(var k = 1;k<data.length;k++){
var row = data[k]
var merge = row[0]+" "+row[1]
ws.getRange(k+1,3).setValue(merge)
}
}
This code will simply take values from first and second column and concatenate result will show in third column
