How do implicit casts differ from explicit casts in JavaScript?

In this article, you will learn how implicit casts differ from explicit casts in JavaScript.

Implicit cast is the automatic conversion of a value from one data type to another. It is also called type conversion.

Explicit coercion is to convert the data type according to the user's needs.

Example 1

In this example, let us understand implicit casts.

let inputValue = "5" console.log("The input variable is defined as: ") console.log(inputValue, typeof inputValue); let resultValue = Number(inputValue); console.log("The input variable is defined as: ") console.log(resultValue, typeof resultValue);

illustrate

• Step 1- Define a variable: inputValue and assign an integer.

• Step 2- Add an empty string to "inputValue". The type of 'inputValue' is now changed from number to string.

• Step 3- Display the values and their types as results.

Example 2

In this example, let us understand explicit cast.

let inputValue = "5" console.log("The input value is defined as a string with value: ", inputValue) let resultValue = Number(inputValue); console.log("The result value after conversion to a number is :", resultValue)

illustrate

• Step 1- Define a variable: inputValue and assign it a string value.

• Step 2- Convert string value type to integer. Now the type of 'inputValue' is changed from string to number.

• Step 3- Display the values and their types as results.
