JavaScript: Check whether the characters a and b are separated by exactly 3 places anywhere in a given string
JavaScript Basic: Exercise-53 with Solution
Write a JavaScript program to check whether the characters a and b are separated by exactly 3 places anywhere (at least once) in a given string.
Visual Presentation:
Sample Solution:
JavaScript Code:
// Define a function named ab_Check with parameter str
function ab_Check(str) {
// Use regular expressions to check if the pattern 'a...b' or 'b...a' exists in the given string
// The test() method returns true if the pattern is found, otherwise, it returns false
return (/a...b/).test(str) || (/b...a/).test(str);
}
// Log the result of calling ab_Check with the given strings to the console
console.log(ab_Check("Chainsbreak"));
console.log(ab_Check("pane borrowed"));
console.log(ab_Check("abCheck"));
Output:
true true false

Flowchart:
ES6 Version:
// Define a function named ab_Check with parameter str
const ab_Check = (str) => {
// Use regular expressions to test if the string contains either "a...b" or "b...a" patterns
return (/a...b/).test(str) || (/b...a/).test(str);
};
// Log the result of calling ab_Check with the given strings to the console
console.log(ab_Check("Chainsbreak"));
console.log(ab_Check("pane borrowed"));
console.log(ab_Check("abCheck"));
