  2. Increment and decrement operators - Wikipedia

    en.wikipedia.org/wiki/Increment_and_decrement...

    The pre-increment and pre-decrement operators increment (or decrement) their operand by 1, and the value of the expression is the resulting incremented (or decremented) value. The post -increment and post -decrement operators increase (or decrease) the value of their operand by 1, but the value of the expression is the operand's value prior to ...

  3. PHP syntax and semantics - Wikipedia

    en.wikipedia.org/wiki/PHP_syntax_and_semantics

    The concatenation operator is . (dot). Array elements are accessed and set with square brackets in both associative arrays and indexed arrays. Curly brackets can be used to access array elements, but not to assign. PHP has three types of comment syntax: /* */ which serves as block comments, and // as well as # which are used for inline comments ...

  4. For loop - Wikipedia

    en.wikipedia.org/wiki/For_loop

    Depending on the language, an explicit assignment sign may be used in place of the equal sign (and some languages require the word int even in the numerical case). An optional step-value (an increment or decrement ≠ 1) may also be included, although the exact syntaxes used for this differ a bit more between the languages.

  5. JavaScript syntax - Wikipedia

    en.wikipedia.org/wiki/JavaScript_syntax

    The binary logical operators returned a Boolean value in early versions of JavaScript, but now they return one of the operands instead. The left–operand is returned, if it can be evaluated as : false , in the case of conjunction : ( a && b ), or true , in the case of disjunction : ( a || b ); otherwise the right–operand is returned.

  6. Fat comma - Wikipedia

    en.wikipedia.org/wiki/Fat_comma

    The fat comma (also termed hash rocket in Ruby and a fat arrow in JavaScript) is a syntactic construction that appears in a position in a function call (or definition) where a comma would usually appear. The original usage refers to the ")letters:(" construction in ALGOL 60. Newer usage refers to the "=>" operator present in some programming ...

  8. Augmented assignment - Wikipedia

    en.wikipedia.org/wiki/Augmented_assignment

    Augmented assignment (or compound assignment) is the name given to certain assignment operators in certain programming languages (especially those derived from C).An augmented assignment is generally used to replace a statement where an operator takes a variable as one of its arguments and then assigns the result back to the same variable.

  9. Operator (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Operator_(computer...

    The semantics of operators particularly depends on value, evaluation strategy, and argument passing mode (such as Boolean short-circuiting). Simply, an expression involving an operator is evaluated in some way, and the resulting value may be just a value (an r-value), or may be an object allowing assignment (an l-value).
