The “if…else” statement allows you to execute different blocks of code based on a condition. If the condition is true, the code inside the “if” block runs; otherwise, the code inside the “else” block executes.
The “switch case” statement provides an alternative to multiple “if…else” statements. It allows you to check a variable against different cases and execute code based on the matching case.
The “for” loop is used for repeating a block of code a specific number of times. It consists of an initialization, a condition, an increment/decrement statement, and the code to be executed in each iteration.
The “while” loop repeatedly executes a block of code as long as a specified condition is true. It checks the condition before each iteration.
Regular expressions (RegExp) are used to match patterns in strings. They provide a powerful way to search, replace, and validate strings based on specific patterns and rules.
