Yes, JavaScript strings are immutable. This means that once a string is created, its value cannot be changed.
If you try to modify a string, instead of altering the original string, JavaScript will create a new string with the desired modifications.
#javascript
let str = "hello";
str[0] = "H"; // This won't change the string
console.log(str); // Outputs: "hello"
str = "Hello"; // This creates a new string and assigns it to the variable
console.log(str); // Outputs: "Hello"
In this case, although you tried to change the first character of str
, the string itself remained unchanged. The modification creates a new string instead of altering the original one.
How Coding Filters Improve Code Efficiency!
Coding filters enhance the efficiency of code by allowing developers to target and process only relevant data. This reduces the need for unnecessary loops, conditional checks, and repetitive logic, leading to faster execution times and optimized resource usage in your applications.
