TypeScript String to Number Conversion Methods

- Using Number() Constructor
- Number() constructor converts strings to numbers, returning NaN for invalid values
- Unary plus (+) operator can be used but should be avoided for number addition
- Both approaches provide correct typing and TypeScript type inference
- Using parseInt/parseFloat
- parseInt converts strings to integers, parseFloat to floating-point numbers
- Functions return NaN for invalid first non-whitespace characters
- TypeScript can infer type from NaN, making these functions reliable
- Using replace Method
- replace() removes non-digit characters from string
- Empty string conversion returns 0, requiring type checking
- Regular expression with \D flag can be used for more complex cases
- Replace method should be used only when other methods fail
