String Concatenation in JavaScript

Javascript Buffered String (kinda)

// old concatenation (creates a new variable in memory for each +)
var stuckTogetherOld = "value1" + "value2" + "value3";

// Better:

// Front End Performance Tip for string concatenation or JS Templates
var stuckTogether = ["value1", "value2", "value3"].join("");

// Quicker to execute
var tmpl = ''.concat(
  '<div>',
    '<span>foo<span>',
  '</div>'
);
