Compute constant value

Computes value of the current expression and replace it (e.g. 1 + 1 replaced by 2)

Convert bin to dec (ES6)

Converts numeric literal from binary to decimal form

Convert concatenation to template string

Converts string and arguments concatenation to template string

Convert 'if' statement to ternary expression

Works on 'if' statement that returns value or performs assignment inside each branch. It converts the statement to a ternary expression ('x ? a : b')

Convert 'if' to 'switch'

If the same expression is checked against several values for strict equality, 'if' statement may be converted to 'switch'

Convert object literal get-accessor to simple property

Converts ECMAScript 5 get-accessor to simple property

Convert object literal property to accessors pair with backing field

Converts object literal property to ECMAScript 5 accessors pair with backing field

Convert object literal property to get-accessor

Converts object literal property to ECMAScript 5 get-accessor

Convert oct to dec (ES6)

Converts numeric literal from binary to decimal form

Convert property assignment in constructors to accessor property definition with backing field

Converts property assignment in constructors to accessor property definition via Object.defineProperty() call

Convert property assignment in constructors to data property definition

Converts property assignment in constructors to data property definition via Object.defineProperty() call

Convert property assignment in constructors to get-accessor property definition

Converts property assignment in constructors to get-accessor property definition via Object.defineProperty() call

Convert ternary expression to 'if' statement

Converts ternary expression whose value is returned or assigned to an 'if' statement

Convert to bin (ES6)

Converts numeric literal from decimal to binary form

Convert to dec

Converts numeric literal from hexadecimal to decimal form

Convert to dec

Converts numeric literal from octal to decimal form

Convert to hex

Converts numeric literal from decimal to hexadecimal form

Convert to oct

Converts numeric literal from decimal to octal form

Converts expression lambda to block lambda with return

Converts expression lambda to block lambda with return

Converts single-return block lambda to expression

Converts single-return block lambda to expression lambda

Create From Usage

Creates property, function, local variable or parameter from usage

For more information, see Generate code from usage.

Flip operator arguments

Flips left and right arguments for selected operator e.g. null == x to x == null.

Flip relational expression

Flips the current relational expression e.g. x > 1 to x < 1.

Introduce variable from expression statement

Introduces variable from expression statement

Invert 'if' statement

Inverts guard condition of an 'if' statement and swaps the branches' code accordingly

Invert ternary condition

Inverts condition and swaps branches of a ternary expression

Join local variable declaration and assignment

Works on an assignment to a variable that was declared without initializer. Moves the declaration to the current point and merges it with the assignment.

Join string literals

Concatenates two string literals into one

Merge nested 'if' statements

Merges two nested 'if' statements to a single 'if' statement that checks conjunction of the original conditions.

Merge two 'if' statements

Merges 'if' statement with nested 'if' statement in else branch with equal body to a single 'if' statement that checks disjunction of the original conditions.

Negate logical expression

Negates logical expression

Remove braces

Removes unnecessary braces around one or more statements in the code

Remove redundant parenthesis

Removes parenthesis in case they are redundant

Replace logical expression with equal expression

Replace logical expression with equal expression

Replace single-quoted string literal with double-quoted

Replace single-quoted string literal with double-quoted and vice versa

Reverse assignment statement

Reverses source and destination parts of an assignment statement.

Split 'if' with '&&'-condition into nested 'if'-statements

Works on an 'if' statement, whose value is a conjunction ('&&') of two simpler conditions. It converts the 'if' statement into two nested 'if' statements.

Split 'if' with '||'-condition into two 'if'-statements

Works on an 'if' statement, whose condition is a disjunction ('||') of two simpler conditions. It converts the 'if' statement into two 'if' statements with equal bodies.

Split into separate declarations

Works on variable declaration or lexical declaration statement that declares multiple variables. It splits such statement into multiple statements each declaring a single variable.

Split 'return' statement of boolean value to 'if' statement

Works on a 'return' statement, whose value is of the boolean type. It converts the 'return' statement into an 'if' statement with two 'return' statements, returning 'true' and 'false' values.

Split 'return' with '&&'-condition into guarding 'if' and 'return'

Works on a 'return' statement, whose condition is a conjunction ('&&') of two simpler conditions. It converts the 'return' statement into a guarding 'if' statement and a 'return'.

Split 'return' with '||'-condition into assignment to temporary variable, 'if'-statement and 'return'

Works on a 'return' statement, whose value is a disjunction ('||') of two simpler conditions. It converts the 'return' statement into a guarding 'if' statement and a 'return'.

Split variable declaration and assignment

Moves variable initializer from declaration statement to separate assignment statement.
