How to Replace Specific Strings in an Array of Strings in JavaScript?

How can I replace specific strings in an array of strings using JavaScript?

const myArray = ['apple', 'banana', 'orange']; // Code to replace 'banana' with 'grape'

In JavaScript, you can easily replace specific strings within an array using various methods such as `map()`, `forEach()`, or traditional loops. This allows dynamic updates to your array based on conditions or specified replacements.

const myArray = ['apple', 'banana', 'orange'];
const updatedArray = myArray.map(item => item === 'banana' ? 'grape' : item);
console.log(updatedArray); // Outputs: ['apple', 'grape', 'orange']

Causes

• The need to update an array to reflect changes in data.
• Specific strings need to be replaced based on application requirements.

Solutions

• Using the `map()` method to create a new array with replaced values.
• Utilizing the `forEach()` method for in-place updates, if mutability is acceptable.
• Applying traditional loops to conditionally replace items.

Mistake: Using the `replace()` method instead of `map()`, which won't work directly on arrays.

Solution: Use `map()` for creating a new array while replacing items.

Mistake: Not handling cases where the string may not exist in the array.

Solution: Consider adding fallback logic to ensure desired behavior.
