Learn essential coding patterns to answer problems and prepare for tech companies' interviews.

Ace the JavaScript Coding Interview

This module teaches us the underlying patterns behind common coding interview questions. By learning these essential patterns, we'll be able to unpack and answer any problem the right way—just by assessing the problem statement. This approach was created by FAANG hiring managers to help us prepare for the typical rounds of interviews at major tech companies like Apple, Google, Meta, Microsoft, and Amazon.

By the end of this module, we'll have the skills we need to unlock even the most challenging questions, grok the coding interview, and level up our career with confidence.

Coding Interview Patterns

# Statement
Given a string that may consist of opening and closing parentheses, your task is to check whether or not the string contains valid parenthesization.

The conditions to validate are as follows:
1) Every opening parenthesis should be closed by the same kind of parenthesis.  Therefore, `{)`and `[(])` strings are invalid.

2) Every opening parenthesis must be closed in the correct order.  Therefore, `)(` and `()(()` are invalid.

**Constraints:**

* $1 \leq$  `s.length` $\leq 10^3$
* The string will only contain the following characters: `(`, `)`, `[`, `]`, `{` and `}`.
