I would like to join a js variable together with another to create another variable name... so it would be look like;
for (i=1;i<=2;i++){
var marker = new google.maps.Marker({
position:"myLatlng"+i,
map: map,
title:"title"+i,
icon: "image"+i
});
}
and later on I have
myLatlng1=xxxxx;
myLatlng2=xxxxx;

Concatenation is the process of appending one string to the end of another string. You concatenate strings by using the + operator. For string literals and string constants, concatenation occurs at compile time; no run-time concatenation occurs. For string variables, concatenation occurs only at run time.
The same + operator you use for adding two numbers can be used to concatenate two strings. You can also use += , where a += b is a shorthand for a = a + b . If the left hand side of the + operator is a string, JavaScript will coerce the right hand side to a string.
The concat() method joins two or more strings. The concat() method does not change the existing strings. The concat() method returns a new string.
The concat() method concatenates a string argument to the calling string and returns a new string. In the examples below, we will take two strings and combine them using the concat() method. As you may have noticed, the concat() method takes a variable number of arguments.
Use the concatenation operator +, and the fact that numeric types will convert automatically into strings:
var a = 1;
var b = "bob";
var c = b + a;
ES6 introduce template strings for concatenation. Template Strings use back-ticks (``) rather than the single or double quotes we're used to with regular strings. A template string could thus be written as follows:
// Simple string substitution
let name = "Brendan";
console.log(`Yo, ${name}!`);
// => "Yo, Brendan!"
var a = 10;
var b = 10;
console.log(`JavaScript first appeared ${a+b} years ago. Crazy!`);
//=> JavaScript first appeared 20 years ago. Crazy!
