Check Two Strings and Return Common Words in JavaScript
We are required to write a JavaScript function that takes in two strings as arguments. The function should then check the two strings for common characters and prepare a new string of those characters.
Lastly, the function should return that string.
The code for this will be −
Example
const str1 = "IloveLinux"; const str2 = "weloveNodejs"; const findCommon = (str1 = '', str2 = '') => { const common = Object.create(null); let i, j, part; for (i = 0; i < str1.length - 1; i++) { for (j = i + 1; j <= str1.length; j++) { part = str1.slice(i, j); if (str2.indexOf(part) !== −1) { common[part] = true; } } } const commonEl = Object.keys(common); return commonEl; }; console.log(findCommon(str1, str2));
Output
And the output in the console will be −
[ 'l', 'lo', 'lov', 'love', 'o', 'ov', 'ove', 'v', 've', 'e' ]
