fuzzySearch

Determines if the patrn matches with str

Loops through str and determines if it contains all characters of patrn and in the correct order. Both the strings are converted to lower case.

Taken from here.

fuzzySearch = (patrn, str) => {
    const pattern = patrn;
    const string = str; 
    let patternIdx = 0;
    let strIdx = 0;
    let patternLength = pattern.length;
    let strLength = string.length;

    while (patternIdx !== patternLength && strIdx !== strLength) {
        let patternChar = pattern[patternIdx].toLowerCase();
        let strChar = string[strIdx].toLowerCase();
        if (patternChar === strChar)
            ++patternIdx;
        ++strIdx;
    }

    return patternLength !== 0 && strLength !== 0 && patternIdx === patternLength ? true : false;
}

fuzzySearch('rt','Rohit); // true
fuzzySearch('tr','Rohit); // false
