To check if a given string is isomorphic in JavaScript, you would need to write a function that compares two strings and determines if they are isomorphic. Two strings are considered isomorphic if there is a one-to-one mapping between each character of the first string and each character of the second string, and all occurrences of a character in the first string map to the same character in the second string.
Here is a JavaScript function based on the information provided in the search results:
javascriptCopy
function isIsomorphic(str1, str2) {
if (str1.length !== str2.length) {
return false;
}
const mapping = {};
const mappedValues = new Set();
for (let i = 0; i < str1.length; i++) {
const char1 = str1[i];
const char2 = str2[i];
// If char1 has not been seen before
if (!mapping[char1]) {
// If char2 is already mapped, return false
if (mappedValues.has(char2)) {
return false;
}
// Map char1 to char2 and add char2 to the set of mapped values
mapping[char1] = char2;
mappedValues.add(char2);
} else {
// If char1 is already mapped to a different char, return false
if (mapping[char1] !== char2) {
return false;
}
}
}
return true;
}
This function first checks if the two strings have the same length. If the...
