Info

2 numerically. "A" === "\u0041" Strings have a length property. For example, "seven".length is 5. Strings are immutable. Once it is made, a string can never be changed. But it is easy to make a new string by concatenating other strings together with the + operator. Two strings containing exactly the same characters in the same order are considered to be the same string. So: 'c' + 'a' + 't' === 'cat' is true. Strings have methods (see Chapter 8): 'cat'.toUpperCase( ) === 'CAT' 2
2.5. Statements A compilation unit contains a set of executable statements. In web browsers, each tag delivers a compilation unit that is compiled and immediately executed. Lacking a linker, JavaScript throws them all together in a common global namespace. There is more on global variables in Appendix A. When used inside of a function, the var statement defines the function's private variables. The switch, while, for, and do statements are allowed to have an optional label prefix that interacts with the break statement. 1 1
