Uncovering the Mysteries of Type Coercion in JavaScript

Type Coercion refers to the process of automatic or implicit conversion of values from one data type to another. This includes conversion from Number to String, String to Number, Boolean to Number etc. when different types of operators are applied to the values.

Type coercion in JavaScript refers to the process of converting a value from one data type to another automatically. This happens when different data types are used in the same operation or when a value is compared to a value of a different data type.

For example, when a string is added to a number, JavaScript will automatically convert the string to a number before performing the addition. Similarly, when a non-boolean value is used in a boolean context, JavaScript will convert the value to a boolean using a set of rules.

JavaScript uses a set of rules to determine the type of a value when performing type coercion, these rules are called type coercion rules. For example, in JavaScript empty string, 0, null, undefined, NaN are considered as falsy values, and all other values are considered as truthy.

Type coercion can also occur when comparing values of different data types. For example, when comparing a string to a number, JavaScript will convert the string to a number before making the comparison.

It's important to be aware of type coercion when writing JavaScript code, as it can lead to unexpected behavior if not handled properly. To avoid type coercion issues, it's best practice to explicitly convert the data types when necessary.
