Specifications

These operators provide string functions using operators. Many other string functions are available,

see String.

str1 + str2

This operator returns a string that is the concatenation of its

operands, (str1 and str2).

+ string operator

See also += assignment operator.

Logical operators

These operators are used to evaluate whether their operands are true or false. The binary operators

use short-circuit logic, that is, they do not evaluate their second operand if the logical value of

the expression can be determined by evaluating the first operand alone.

operand1 && operand2

This operator returns an object whose value is true if both its operands are

true; otherwise it returns an object whose value is false.

&& operator

Specifically, if the value of operand1 is false, the operator returns operand1

as its result. If operand1 is true, the operator returns operand2.

operand1 || operand2

This operator returns an object whose value is true if either of its operands

are true; otherwise it returns an object whose value is false.

|| operator

Specifically, if the value of operand1 is true, the operator returns operand1

as its result. If operand1 is false, the operator returns operand2.

! operand

If the operand's value is true, this operator returns false; otherwise it returns

true.

! operator

Comparison operators

These operators are used to compare objects and their values.
