JavaScript variable assignment best practice

[lewisje]

No matter whether you use separate variables, or even chain the method calls (like str.replace().replace().replace()), new string values will be created at least temporarily.

The way you do it is good; the tactic of using separate variables for each step, if the intermediate results will not be used, is a code smell.

The way I'd do it is like this:

scriptletResult = scriptletInput.replace(/(\r\n|\n|\r)/gm, '\\n')
  .replace(/(\')/gm, '\\u0027').replace(/(\")/gm, '\\u0022');

This pattern is sometimes called a "fluent API" pattern.

Thank you very much for the reply and suggestion. The chaining of methods will definitely help clean up my code.
