How do I check if two strings have the same characters?

Method 2 (Count characters)

  1. Create count arrays of size 256 for both strings. Initialize all values in count arrays as 0.
  2. Iterate through every character of both strings and increment the count of character in the corresponding count arrays.
  3. Compare count arrays. If both count arrays are same, then return true.

What is == and === in JavaScript?

= is used for assigning values to a variable in JavaScript. == is used for comparison between two variables irrespective of the datatype of variable. === is used for comparision between two variables but this will check strict type, which means it will check datatype and compare two values.

What is difference between == equals () and compareTo () method?

compareTo: Compares two strings lexicographically. equals: Compares this string to the specified object. compareTo compares two strings by their characters (at same index) and returns an integer (positive or negative) accordingly. equals() can be more efficient then compareTo().

Why does JavaScript have 3 equal signs?

The triple equals operator ( === ) returns true if both operands are of the same type and contain the same value. If comparing different types for equality, the result is false. This definition of equality is enough for most use cases. When comparing the string “0” and the number 0 the result is false as expected.
