A brief explanation to what hoisting means in the JavaScript programming languageJavaScript before executing your code parses it, and adds to its own memory every function and variable declarations it finds, and holds them in memory. This is called hoisting....
There are lots of different type conversions described in the spec. One of them isToInteger. JavaScript uses it when a standard function expects an integer argument. Before the use of the passed argument, JavaScript appliesToIntegerto the value of that argument. If the value is NaN, thenToIn...
Nashorn, the new JavaScript engine Removal of the Permanent Generation and more… The best way to read this book is with a Java 8 supporting IDE running so you can try out the new features. Code examples can be found ongithub. 2.Lambda Expressions ...
For example, JavaScript has methods, such as charAt() and charCodeAt(), that return values related to the calling string. The charAt() method, for example, returns a string containing one character, which is the character at the location given as a parameter to the function. Running the ...
out+=str.charAt(i); }elseif(c > 0x07FF) { out+= String.fromCharCode(0xE0 | ((c >> 12) & 0x0F)); out+= String.fromCharCode(0x80 | ((c >> 6) & 0x3F)); out+= String.fromCharCode(0x80 | ((c >> 0) & 0x3F)); ...
charAt(index)- return the character at the index (starting at 0) concat(left, right)- concatenate the two string together endsWith(suffix)- returns true if the string has the suffix startsWith(prefix)- returns true if the string has the prefix ...
