If you know in advance that you will be building larger strings, it can be beneficial to initialize it with sufficient size in advance, so that the internal buffer does not need to be resized: If you are producing many strings, it is advisable to reuse StringBuilders: If (and only if) multiple threads are writing to the same buffer, use StringBuffer, which is a synchronized version of StringBuilder. JavaScript differentiates between the string primitive, an immutable datatype, and the String object.In order to test the difference between the two, we will initialize a string primitive and a string object.We can use the typeof operator to determine the type of a value.
