  2. ArkTS - Wikipedia

    en.wikipedia.org/wiki/ArkTS

    ArkTS was designed to be safe and friendly to new programmers while not sacrificing speed. By default ArkTS manages all memory automatically and ensures variables are always initialized before use. Array accesses are checked for out-of-bounds errors and integer operations are checked for overflow. Parameter names allow for the creation of clear ...

  3. Dart (programming language) - Wikipedia

    en.wikipedia.org/wiki/Dart_(programming_language)

    To run in mainstream web browsers, Dart relies on a source-to-source compiler to JavaScript. This makes Dart apps compatible with all major browsers. Dart optimizes the compiled JavaScript output to avoid expensive checks and operations. This results in JavaScript code that can run faster than equivalent code handwritten in plain JavaScript. [33]

  4. JavaScript syntax - Wikipedia

    en.wikipedia.org/wiki/JavaScript_syntax

    Rest parameters are similar to Javascript's arguments object, which is an array-like object that contains all of the parameters (named and unnamed) in the current function call. Unlike arguments, however, rest parameters are true Array objects, so methods such as .slice() and .sort() can be used on them directly.

  5. Entry point - Wikipedia

    en.wikipedia.org/wiki/Entry_point

    The entry point is the first function that is executed when a program runs. In Dart, the entry point is typically a function named main. When a Dart program is run, the Dart runtime looks for a function named main and executes it. Any Dart code that is intended to be executed when the program starts should be included in the main function.

  6. Foreach loop - Wikipedia

    en.wikipedia.org/wiki/Foreach_loop

    The iteration form of the Eiffel loop can also be used as a boolean expression when the keyword loop is replaced by either all (effecting universal quantification) or some (effecting existential quantification). This iteration is a boolean expression which is true if all items in my_list have counts greater than three:

  7. Syntactic sugar - Wikipedia

    en.wikipedia.org/wiki/Syntactic_sugar

    Similarly an array element update is a procedure consisting of three arguments, for example set_array(Array, vector(i,j), value), but many languages also provide syntax such as Array[i,j] = value. A construct in a language is syntactic sugar if it can be removed from the language without any effect on what the language can do: functionality and ...

  8. ECMAScript - Wikipedia

    en.wikipedia.org/wiki/ECMAScript

    Previously, JavaScript only supported function scoping using the keyword var, but ECMAScript 2015 added the keywords let and const, allowing JavaScript to support both block scoping and function scoping. JavaScript supports automatic semicolon insertion, meaning that semicolons that normally terminate a statement in C may be omitted in ...

  9. Method chaining - Wikipedia

    en.wikipedia.org/wiki/Method_chaining

    Note that in JavaScript filter and map return a new shallow copy of the preceding array but sort operates in place. To get a similar behavior, toSorted may be used. But in this particular case, sort operates on the new array returned from filter and therefore does not change the original array.
