:used as inline if-else isright associative. In short this means that the rightmost?gets fed first and it takes exactlyoneclosest operand on the left andtwo, with a:, on the right. Practically speaking, consider the following statement (same as above): a ? a : b ? c ? c(b) : b...
the name of functions and variables can't be same, because they only are the vessel to store the memory address. If the name of functions and variables are same, the memory address will be covered // method onefunctionfunc_1(args){ statement;returnvalue }varret=func1()// method twovarf...
比如“程序”,“语句”,“表达式”等,前面的例子中,isPanda('🐼')就会被分析为一条表达语句 ExpressionStatement,isPanda()就会被分析成一个函数表达式 CallExpression,🐼就会被分析成一个变量 Literal 等,众多语法之间的依赖、嵌套关系,就构成了一个树状结构,即 AST 语法树。
然而,不同浏览器在就错误信息上也有可能产生分歧,比如当switch 语句中有多个default 语句时,Chrome会抛出 “More than one default clause in switch statement” 而FireFox会抛出”more than one switch default”. 当新特性加入到JavaScript语言中时,错误信息也应该实时更新。当处理容易产生混淆代码导致的错误时,往往...

IfStmt: an if statement; use IfStmt.getCondition(), IfStmt.getThen() and IfStmt.getElse() to access its condition expression, “then” branch and “else” branch, respectively. LoopStmt: a loop; use Loop.getBody() and Loop.getTest() to access its body and its test expression, respectiv...
Enable "inline" diffs, an alternative output for diffing strings. Useful when working with large strings. Does nothing if an assertion library supplies its own diff output. # --reporter <name>, -R <name> Specify the reporter that will be used, defaulting to spec. Allows use of third-party...
Type the name of the new component. If this name is already used or invalid, PhpStorm shows a warning. Otherwise, a new single-file component is created and imported into the parent component. Inline refactorings Inline refactorings are opposite to Extract refactorings. Example 1: Inline ...
