Currently working on a basic program that requires checking if the input string exists in the array.
To simplify it, for example, if someone types 'Ai', I want the program to display all elements in the array containing the letters 'Ai'. The result should include words like 'Airplane', 'Air', 'Airport', and 'Airfield'.
If anyone has a quick and simple solution for achieving this, your help would be greatly appreciated!
If you have an array consisting of only strings, the following functions can be used to perform the required actions:
// Function to find if any string in the array contains a specific substring.
function checkStringInArray(array: string[], str: string)
{
let filteredArray = array.filter(x => x.includes(str));
return filteredArray.length > 0;
}
// Function to find if any string in the array starts with a particular string.
function checkStringStartsWith(array: string[], str: string)
{
let filteredArray = array.filter(x => x.startsWith(str));
return filteredArray.length > 0;
}
Example program for testing:
let testStr: string = "air";
let exampleArr1 = ["corsair","stenographer"];
let exampleArr2 = ["hey","no"];
function checkStringInArray(array: string[], str: string)
{
let filteredArray = array.filter(x => x.includes(str));
return filteredArray.length > 0;
}
function checkStringStartsWith(array: string[], str: string)
{
let filteredArray = array.filter(x => x.startsWith(str));
return filteredArray.length > 0;
}
console.log(checkStringInArray(exampleArr1, testStr));
console.log(checkStringInArray(exampleArr2, testStr));
console.log(checkStringStartsWith(exampleArr1, testStr));
console.log(checkStringStartsWith(exampleArr2, testStr));
Output:
true false false false
