Looking to develop a TypeScript function that can take an array of any type as input, calculate the number of elements present in it, and return the count.
An example output would be: If user inputs: ["soccer", "basketball"] Then output: 2
Any suggestions on how to tackle this problem using TypeScript?
Utilizing the generic type T provides flexibility to accept arrays of any type as parameters.
calculateArrayLength<T>(inputArray:T[]): number {
return inputArray.length;
}
If you're looking for a solution, here's one approach:
// This function takes an array of any type as input and returns the length of the array
function getArrayLength(inputArray : any[]) : number {
return inputArray.length;
}
// Testing the function with an array of length 6
const testArray = ['a', 'b', 'c', 1, 2, 3];
// Expected output: 6
console.log(getArrayLength(testArray));
