The time complexity can be constant O(1) for interned strings. It appears that interning occurs solely for directly assigned strings such as var str = "test"; , and not for strings built through concatenation using for-loops or functions. The time complexity...
For the same string value, no matter it is used in several places in the program, the compiler only needs to allocate a piece of storage for it, which greatly improves the storage utilization. 2. There is no trailing '\0', the length of the string is stored ...
