box by a user against a known string in your code. Because the user might include a variety of case variations in the entry, you need to guard against unorthodox entries by converting the input text to all uppercase or all lowercase letters for comparison (seeTesting Equality of Two Strings...
For example, each of the following is valid JavaScript for assigning a string to a variable: x=‘string’; x=“string”; (x)=(‘string’); this.x=‘string’; x={‘a’:’string’}.a; [x,y,z]=[‘string1’,’string2’,’string3’]; x=/z(.*)/(‘zstring’)[1]; x=‘...
public static void main(String[] args) { { // block starts int foo = 4; } // block ends System.out.println(foo); // Error: cannot find symbol } 在前面的代码中,变量foo只能在直接包围它的块内部访问。如果我们在块结束后尝试访问它,将会得到编译错误。 相比之下,JavaScript 的变量是函数作用...
