- Type coercion is the automatic conversion of data types in JavaScript to enable comparisons and operations
- In this case, the
==operator triggers type coercion, converting the string"5"to a number5before comparing both values - While the values are of different data types, type coercion allows for comparison, resulting in
truebecause5 == 5is true.
