Class StringOps::ConcatenationNode
A data flow node that performs a string concatenation or occurs as an operand in a string concatenation.
For example, the expression x + y + z contains the following concatenation
nodes:
- The leaf nodes
x,y, andz - The intermediate node
x + y, which is both a concatenation and an operand - The root node
x + y + z
Note that the following are not recognized a string concatenations:
- Array
join()calls with a non-empty separator - Tagged template literals
Also note that all + operators are seen as string concatenations,
even in cases where it is used for arithmetic.
Examples of string concatenations:
x + y
x += y
[x, y].join('')
Array(x, y).join('')
`Hello, ${message}`
